What is an apex predator?

Back

An apex predator is a predator at the top of a food chain that has no natural predators of its own.

Front

What factors impact ecological tolerance?

Back

Factors that impact ecological tolerance include temperature, moisture, and nutrient availability, but not the level of biodiversity.

Front

How does proximity to the mainland affect island biodiversity?

Back

Islands closer to the mainland typically have higher levels of biodiversity due to easier access for species migration.

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of stages from pioneer species to a climax community.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously uninhabited land, initiating the process of ecological succession.

Front

What role do keystone species play in an ecosystem?

Back

What is the difference between primary and secondary succession?

Back

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species and genetic diversity.
