Both agricultural ecosystems and coral reef ecosystems recycle matter, but the amount of nutrient recycling varies between the two ecosystems.

In an agricultural ecosystem, farmers often use fertilizers to replenish soil nutrients and promote plant growth. However, excess fertilizer can leach into groundwater or run off into nearby bodies of water, causing nutrient pollution.

In contrast, coral reef ecosystems are highly efficient at recycling nutrients. The coral itself provides a substrate for the growth of algae and other microorganisms, which in turn provide nutrients for the coral. Coral reefs also support a diverse array of organisms, including filter feeders like sponges, which can remove nutrients from the water column and recycle them.

Overall, coral reef ecosystems tend to recycle more nutrients than agricultural ecosystems, as they have evolved to efficiently cycle nutrients within the system. Agricultural ecosystems can experience nutrient loss through leaching and runoff, which can result in pollution of nearby water bodies.

However, sustainable agricultural practices such as crop rotation and composting can also enhance nutrient cycling and reduce nutrient loss.

Fragmentation is a form of asexual reproduction and is seen in annelids, fungi, cyanobacteria, sponges, and flatworms.

In Fragmentation, an organism divides itself into a number of fragments. It occurs when an organism completely breaks down independently irrespective of the other parts. Each one of these fragments matures into fully grown adults that are clones of the original organism.

Asexual reproduction usually involves the participation of a single parent alone can produce new offspring. The newly produced individual is genetically identical to one another and its parent. Both multicellular and unicellular organisms divide by fragmentation which is asexual reproduction.

Fragmentation is the most common method of reproduction in lower invertebrates. It is seen in many organisms including filamentous cyanobacteria, algae, lichens, molds, many plants, and animals such as flatworms,  annelid worms, sponges, and sea stars.

The organisms that can reproduce by fragmentation are Option d Sponges and Sea anemones.

Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.

Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.

Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.

Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D

Answer:

Darwin's theory of evolution state that"all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce".

Answer:

The above speaks to the formation of elements such as Iron and Carbon. The description for these are given below.

5) A According to scientific research, it is to be noted that during the final evolutionary stages of massive stars, heavy elements are formed through neutron capture.

These elements result from a chain of nuclear reactions as the star exhausts its fuel.

The process ultimately leads to atomic nuclei fusing to create heavier elements with aid from gravitational pressure and collapsing core energy.

It is critical to note that , supernova explosions disperse these synthesized heavy elements into space where subsequent stars and planets incorporate them.

6)

Primarily composed of hydrogen and helium during its emergence, a star carries the above elements at formation.

Hydrogen burning within the core initiates a series of nuclear reactions whereupon fusing creates these metals with increasing complexity that include Carbon.

Thus over time and after discharge following explosions certain elements reintegrate in new cosmic environments building on previous chemical processes .

Carbon ends up in the human body via the consumption of plants and other organisms that make use of the process of photoynthesis.

Answer:

Primary succession

Explanation:

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited. In other words, it is the gradual growth of an ecosystem over a longer period of time.

Catalase breaks down poisonous hydrogen peroxide into water and oxygen gas.

All enzymes, including catalase, are proteinous in nature. All enzymes also have their substrates, and they are quite specific with them. An enzyme that acts on a particular substrate may not act on another.

Catalase is an enzyme whose substrate is hydrogen peroxide. In cells, catalase helps with the homeostasis of hydrogen peroxide. Once the chemical starts building up beyond a certain concentration threshold, catalase starts breaking it down.

Catalase is able to break down hydrogen peroxide into two components - water and oxygen gas.

Thus, the option that best describes the function of the enzyme catalase is the third option.

Explanation:

After incubation, the plate has 54 colonies, indicating that the original Milk sample contained 540,000 CFU/ml.

The equation for calculating the CFU/mL in the original sample is:

CFU/mL = (number of colonies on plate x dilution factor) / volume of the culture plated

Here,

Number of colonies on plate = 54

Volume of the culture plated = 1 mL

The original sample is serially diluted in a proportion of 1:10, that is 1/10

So the dilution of first tube = 1/10

From the first tube, the culture in again diluted in a proportion of 1:10

So, Dilution of second tube = 1/10

The total dilution of tube 2 will be the product of the dilution of tube 1 and tube 2.

So, total dilution of tube 2 = 1/10 x 1/10 = 1/100

Similarly, the total dilution of tube 3 will be 1/1000 and tube 4 will be 1/10000

The sample is plated from tube 4, and therefore the total dilution of tube 4 is used for the calculation of bacterial concentration.

Dilution factor = Reciprocal of dilution

So, dilution factor of tube 4 = 10000 = 104

Substitute the values in the equation:

CFU/mL = ( 54 x 104) / 1 = 54 x 104 = 540000 cells/mL

Explanation:

The concepts of phenotype and genotype are related to genetics.

The phenotype is generally called the external appearance of the living thing, which is formed by the genetic information and environmental effects.

Genotype is the genetic information that an organism carries in its DNA.

For example; Character A is the favorite black color. a is the blue color character.

While the Aa display shows the individual with black eyes in the phenotype, the genotype is expressed as heterozygous dominant black eyes.

Fire requires three things heat, fuel, and oxygen. The heat source is a match. The firewood burns and provides its own heat to keep it burning.  Fire needs oxygen, which can be obtained from fresh air. Air gets hot and denser.

When fire burns, heat transfers kinetic energy to the molecules. As the kinetic energy increases, there are more collisions between molecules. The hot air becomes less dense. As less dense than the cold air around it, the hot air rises and carries the smoke with it. Therefore, the smoke moves away with the wind.

Answer:

Homologous characters indicate descent through modification from a common ancestor.

Explanation:

Homologous characters have the same fundamental structures. They also share the same relations with adjacent structures, and they have the same embryological development.    

These structures might show variations between organisms exhibiting them, according to their function and to the environment in which the organism lives.  

These homologous characters are common in organisms related and that share a common ancestor.  

For example, whales, humans, and horses all have the same bones in the same order, but they matured differently in later embryological development. This is an example of homologous characters.

Homologous characters indicate descent through modification from a common ancestor.

and also by comparing the DNA of the two species. The more nitrogenous bases and amino acids two species have in common, the more closely related they are.

An example of homologous structures is the forelimbs of vertebrates, where the wings of bats and birds, the arms of primates, the front flippers of whales and the forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure.

D.There will be more producers than herbivores in an ecosystem

Explanation:

In an ecosystem, organisms feed on one another in order to obtain energy needed for their life processes. The series of chain by which organisms derive energy by feeding on one another is called FOOD CHAIN. A good chain always start with a PRODUCER (an organism capable of synthesizing its own food via photosynthesis). Organisms called HERBIVORES feed directly on the producers, and subsequently CARNIVORES feed on the herbivores.

According to the pyramid of numbers, which shows a graphical display of the number of organisms occupying each trophic level, the producers which are at the bottom of the pyramid are always more in number than any other organism in the food chain. It takes fewer herbivores to consume a large number of producers.
