Bio Ecology Review

What is exponential growth in ecology?

Back

Exponential growth occurs when a population increases by a constant proportion over time, leading to a rapid increase in size when resources are abundant.

Front

What is a density-independent factor?

Back

A density-independent factor is an environmental factor that affects a population regardless of its density, such as natural disasters like floods.

How is energy transferred in a food chain?

Back

Energy is transferred from one trophic level to the next, with only about 10% of the energy being passed on to the next level.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.

Front

What is the relationship between predator and prey populations?

Back

Predator populations often lag behind prey populations because an increase in prey leads to an increase in predators, but it takes time for predator populations to respond.

Front

Define immigration in ecology.

Back

Immigration is the movement of individuals into a population from other areas, contributing to population growth.

Front

Define emigration in ecology.

Back

Emigration is the movement of individuals out of a population to other areas, leading to a decrease in population size.

Front

What is logistic growth?

Back

Logistic growth is a model of population growth that accounts for resource limitations, resulting in a population that grows rapidly at first and then levels off as it reaches carrying capacity.

Front

What is a tertiary consumer?

Back

A tertiary consumer is an organism that eats secondary consumers in a food chain, often at the top of the food web.

Front

What is a primary consumer?

Back

A primary consumer is an herbivore that feeds on producers (plants) in a food chain.
