What is a food pyramid?

Back

A food pyramid is a graphical representation of the food chain that shows the relationship between different organisms in an ecosystem, illustrating how energy and nutrients flow from one level to another.

Front

What does heterotrophic mean?

Back

Heterotrophic refers to organisms that cannot produce their own food and must obtain nutrients by consuming other organisms.

Front

What is biomass?

Back

Biomass is the total mass of living matter in a given area or volume, often used to measure the amount of energy available at different levels of a food chain.

Front

What is genetic diversity?

Back

Genetic diversity refers to the variety of genes within a species, which is important for the health and resilience of populations.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic (living) and abiotic (non-living) components.

Front

What is habitat destruction?

Back

Habitat destruction is the process by which natural habitats are altered or destroyed, often leading to loss of biodiversity and increased extinction rates.

Front

What are the effects of decreased genetic diversity in populations?

Back

Decreased genetic diversity can lead to increased vulnerability to diseases, reduced adaptability to environmental changes, and lower reproductive success.

Front

What is the difference between prokaryotic and eukaryotic organisms?

Back

Prokaryotic organisms are single-celled and lack a nucleus (e.g., bacteria), while eukaryotic organisms have cells with a nucleus and can be unicellular or multicellular (e.g., plants, animals).
