Ecology: Population Review

Front

What is exponential growth in a population?

Back

Exponential growth occurs when a population increases rapidly due to abundant resources and lack of predators, leading to a J-shaped growth curve.

Front

What are abiotic factors in an ecosystem?

Back

Abiotic factors are non-living components that affect ecosystems, such as temperature, wind, precipitation, and soil type.

Front

Define logistic growth in population ecology.

Back

Logistic growth is a model of population growth that shows how a population grows rapidly at first and then slows as it approaches its carrying capacity due to limited resources.

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 role do producers play in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis and form the base of the food chain.

Front

Identify secondary consumers in an ecosystem.

Back

Secondary consumers are organisms that eat primary consumers; examples include snakes and foxes.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components of an ecosystem (like plants and animals), while abiotic factors are non-living components (like water and soil).

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, defined by how organisms obtain energy, such as producers, primary consumers, and secondary consumers.

Front

Explain the concept of ecological succession.

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem, showing how energy and nutrients flow.
