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?

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.

regents of the university of california v. bakke, 438 u.s. 265 (1978), was a landmark decision by the supreme court of the united states. it upheld affirmative action, allowing race to be one of several factors in college admission policy.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
