Front

What term describes the maximum amount of organisms an ecosystem can support?

Back

Front

What type of species are the first to live in a new habitat?

Front

What is a limiting factor in an ecosystem?

Back

Any biotic or abiotic factor that restricts the number of individuals in a population.

Front

What is the difference between exponential and logistic growth?

Back

Exponential growth occurs when resources are unlimited, leading to a rapid increase in population size, while logistic growth occurs when resources are limited, leading to a stabilization of population size at carrying capacity.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

Front

What is a biome?

Back

A large geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions.
