Mass = 55 L x 2 kg/L = 110 kg or 110000 g. ( Liters is cancelled by Liters).

The phenomenon where a non-native species invades an ecosystem and outcompetes the native species causing the native species to decline potentially to extinction is called "invasive species.

It occurs when non-native species, also known as invasive species, establish themselves and thrive in an ecosystem, causing harm to the native species. Invasive species possess traits that give them a competitive advantage over the native species, such as rapid reproduction, efficient resource utilization, and resistance to local predators or diseases.

The consequences of biological invasions can be severe. The invasive species can outcompete native species for resources like food, habitat, and water, leading to a decline in native populations.

They may also directly predate upon or introduce diseases to native species, further exacerbating their decline. In some cases, the native species are pushed to the brink of extinction or even driven to extinction.

Biological invasions are a significant global concern due to their ecological, economic, and social impacts. They can disrupt ecosystem functioning, alter natural habitats, reduce biodiversity, and cause economic losses in industries like agriculture, forestry, and fisheries.

Efforts are made to prevent and control invasive species through monitoring, early detection, and management strategies such as eradication, containment, and control programs to mitigate their negative effects and protect native species and ecosystems.

Survival of fittest best describes evolution. Evolution is  the method by which a species changes over time to accommodate its environment.

Evolution is the shift in a biological population's heritable traits over successive generations. These traits are the expressions of genes, which are passed down through reproduction from parent to offspring. Genetic recombination and mutation frequently result in variation within a population. This variety is subjected to evolutionary processes like natural selection (including sexual selection) and genetic drift, which cause some traits to become more or less prevalent within a population. This is when evolution happens. Heritable traits evolve over successive generations as a result of shifting evolutionary forces that determine whether a trait is prevalent or rare within a population.

The phrase "survival of the fittest," popularised in Charles Darwin's fifth edition of On the Origin of Species (published in 1869), argued that animals most adapted to their environment have the best chances of surviving and procreating. In this theory, he provided an explanation of how to thoroughly and accurately characterise the mechanism and process of natural selection. The reproductive success of an organism can be used to gauge the effectiveness of this physical biology principle.

Answer:

Animals that grow or live in the wild without any human interference are known as wildlife. Importance of wildlife is as follows: Wildlife helps keep the food chain in place and thereby maintain ecological stability.

Explanation:

The term "wildlife" refers to all living organisms that exist in their natural habitat, without any human interference. It includes animals, birds, plants, and other organisms that thrive in forests, oceans, deserts, and other natural environments.

Wildlife is important to us in several ways:
1. Biodiversity: Wildlife plays a crucial role in maintaining biodiversity. Each species contributes to the intricate web of life, and the loss of even one species can have a significant impact on the entire ecosystem. For example, bees play a vital role in pollination, which is essential for the reproduction of many plant species.

2. Environmental balance: Wildlife helps to maintain a balance in ecosystems. Predators, such as lions or wolves, help control the population of herbivores, preventing overgrazing and maintaining the health of vegetation. This balance ensures that resources are distributed appropriately and prevents the dominance of a single species.

3. Ecosystem services: Wildlife provides various ecosystem services that benefit humans. Forests, for instance, serve as a habitat for countless species, help regulate climate, filter air and water, and provide resources like timber and medicinal plants. Wetlands act as natural filters, purifying water and reducing the risk of floods.

4. Cultural and recreational value: Wildlife also holds significant cultural and recreational value. Many communities have strong cultural connections to specific wildlife species, and these species may play important roles in their traditions, rituals, and beliefs. Additionally, observing and interacting with wildlife through activities such as bird-watching or safaris can bring joy and a sense of connection to nature.

5. Scientific and educational purposes: Studying wildlife helps us gain knowledge about different species, their behavior, and their roles within ecosystems. This understanding is crucial for conservation efforts and managing natural resources sustainably. Wildlife education also fosters a sense of environmental awareness and encourages people to become responsible stewards of the planet.

Hence, wildlife encompasses the diverse range of organisms found in their natural habitats. Its importance lies in its contribution to biodiversity, environmental balance, ecosystem services, cultural value, recreational opportunities, and scientific knowledge. Preserving and protecting wildlife is essential for the well-being of both the natural world and human society.

Answer: Negative Effect of Raising Livestock on Water Resources:

Raising livestock contributes to water pollution. According to the United States Environmental Protection Agency (EPA), animal waste is a significant source of water pollution. When animal waste is not adequately managed, it can contaminate nearby water sources, leaving harmful bacteria and nutrients that can impact aquatic life and human health. The EPA estimates that animal feeding operations produce over 500 million tons of manure per year, which is three times the amount of human waste in the United States.

Moreover, raising livestock involves the use of water resources. The amount of water that livestock requires varies depending on many factors such as animal type, weather conditions, and feed production. According to the Food and Agriculture Organization (FAO), raising a cow requires 9900 gallons of water, while raising pigs and chickens requires 700 and 4300 gallons of water, respectively. This creates a significant strain on water resources, especially in areas that already face a water scarcity issue.

Furthermore, raising livestock also contributes to the degradation of riparian habitats. Riparian habitats are those that exist along the banks of rivers and streams. These habitats play an essential role in stabilizing the banks of rivers, filtering pollutants, and providing a natural habitat for aquatic life. However, raising livestock near these areas can result in the trampling of habitats, the destruction of vegetation, and the accumulation of manure. This can lead to erosion, loss of biodiversity, and reduced water quality.

Conclusion:

In conclusion, raising livestock has a negative effect on water resources. By polluting water sources, using significant amounts of water resources, and contributing to the degradation of riparian habitats, the environmental impact of raising livestock poses a significant threat to aquatic life and human health. Unless farming practices are regulated, and best practices are implemented, raising livestock will continue to pose a severe risk to water resources.

Examples of mechanical wear are rutting and scalping. Mechanical wear is the breaking or loss of a surface caused by physical forces. Wear occurs when heavy equipment or cars are used on the ground surface, leaving behind grooves.

Wear can lead to other problems, such as compacted soil and less water going into the soil. On the other hand, flaking is the loss of dirt, which is usually caused by sharp tools or blades on machines or vehicles. This can result in soil compaction, which may be less fertile or have a different texture or structure than the topsoil due to erosion and other problems.

Furrowing and scalping are two practices that should be considered in land control and preservation, as both can harm soil health, plant growth, and ecosystem functioning.
