Unit 1 Ecology Test Review 24-25

Front

What are Density Independent Limiting Factors?

Back

Factors that affect population size regardless of the population's density, such as natural disasters, climate changes, and human activities.

Front

What is the Carrying Capacity of an ecosystem?

Back

The maximum number of individuals of a species that an environment can sustainably support.

Front

Define Trophic Level.

Back

Each step in the transfer of energy and matter within a biological community, representing different levels of the food chain.

Front

What happens to energy as it moves up trophic levels?

Back

Energy is used and lost as heat, resulting in less energy available for organisms at higher trophic levels.

Front

What is Exponential Growth in population dynamics?

Back

A growth pattern where the population size increases rapidly in proportion to the current size, often seen in ideal conditions.

Front

What is a Food Web?

Back

A complex network of feeding relationships among various organisms in an ecosystem, showing how energy and nutrients flow.

Front

What is the significance of Limiting Factors in ecology?

Back

Limiting factors control the growth, abundance, or distribution of a population within an ecosystem.

Front

How does public transportation reduce greenhouse gas emissions?

Back

By decreasing the number of individual vehicles on the road, it reduces carbon dioxide emissions from fossil fuel combustion.

Front

What is the difference between Density Dependent and Density Independent Limiting Factors?

Back

Density Dependent factors are influenced by population density (e.g., competition, predation), while Density Independent factors affect populations regardless of density.

Front

What is the role of producers in a food chain?

Back

Producers, such as plants, convert solar energy into chemical energy through photosynthesis, forming the base of the food chain.
