Front

What is ecological succession?

Back

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

Front

What is a benefit of using solar energy?

Back

Using solar energy reduces reliance on fossil fuels, leading to lower carbon emissions.

Front

Which trophic level accumulates the least amount of toxins?

Back

Autotrophs (producers) accumulate the least amount of toxins in a food web.

Front

What is an independent variable in an experiment?

Back

An independent variable is the factor that is changed or manipulated in an experiment to test its effects.

Front

What happens when an animal population exceeds its carrying capacity?

Back

When a population exceeds its carrying capacity, the death rate typically increases due to limited resources.

Front

Define carrying capacity.

Back

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

Front

What are primary consumers?

Back

Primary consumers are organisms that eat producers (plants) and are typically herbivores.

Front

What is the role of autotrophs in an ecosystem?

Back

Autotrophs, or producers, convert sunlight into energy through photosynthesis, forming the base of the food web.

Front

Explain the concept of biological evolution.

Back

Biological evolution is the change in the inherited traits of a population over generations, driven by natural selection.

Front

What is the significance of biodiversity?

Back

Biodiversity refers to the variety of life in an ecosystem, which contributes to resilience and stability.
