CG Ecology/Behavior Practice

What happens to producers if a secondary consumer population decreases?

Back

Producers would decrease.

Front

What is the formula to calculate the change in population size (dN/dt)?

Back

dN/dt = rN(1 - N/K) where N is the population size, K is the carrying capacity, and r is the growth rate.

Front

How does a population increase in individuals?

Back

A population increases through births and immigration.

Front

Where do photosynthetic organisms get most of their energy?

Back

Photosynthetic organisms primarily get their energy from sunlight.

Front

What is operant conditioning?

Back

Operant conditioning is a learning process where behavior is influenced by the consequences that follow it, either positive or negative.

Front

Define carrying capacity (K).

Back

Carrying capacity (K) is the maximum population size that an environment can sustain indefinitely.

Front

What is the difference between immigration and emigration?

Back

Immigration is the movement of individuals into a population, while emigration is the movement of individuals out of a population.

Front

What role do decomposers play in an ecosystem?

Back

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

Front

What is the significance of the energy pyramid in ecology?

Back

The energy pyramid illustrates the flow of energy through different trophic levels in an ecosystem, showing that energy decreases as it moves up the pyramid.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components of an ecosystem, while abiotic factors are non-living components, such as temperature and water.
