Red squirrels and gray squirrels have been the native species on an island for many years. A few years ago, black squirrels entered this island. The black squirrel is an invasive species. Invasive species aren't native to the ecosystem. They move into an ecosystem because of natural changes or human intervention. Red squirrels and black squirrels have identical food requirements, but gray squirrels have a different diet. What three effects will these events have on the island's squirrel population?

Answers

Answer:

1. There will be direct predation of species.

2. There will be competition for limited resources like breeding sites, prey.

3. Transmission of diseases or they can cause danger to the native species.

Explanation:

Invasive species are species of organisms that are not natural to an ecosystem and move to an ecosystem because of natural changes and human intervention. Islands are prone to the invasion of invasive species because they don't have predators and there is no competition that control populations in their ecosystem. The invasion of black squirrels will lead to competition for limited resources like breeding sites or prey, the black squirrels will begin to predate other squirrels because they have different nutrients requirements and they can transmit diseases to other squirrels if they are carrier.

Answers

Answer:

Decomposer

Explanation: I just did it

An organism that breaks down dead organisms and decomposes is called a decomposer, and the decomposer takes part in the decomposition process by breaking down the dead and mixing with soil.

What is the decomposer's importance?

Decomposers are of great importance as they can maintain the ecosystem by breaking down dead organic matter and recycling nutrients back into it, later, these nutrients are passed from the environment to plants, then to animals, and then back to the environment. Decomposers include bacteria and fungi that consume dead plant and animal material, breaking down complex molecules into simpler compounds that can be used by plants to grow.

Hence, an organism that breaks down dead organisms and decomposes is called a decomposer, and the decomposer takes part in the decomposition process by breaking down the dead and mixing with soil.
