Front

What is a density dependent limiting factor?

Back

A factor that regulates the maximum size of a population based on the population's density, such as food availability, predation, and disease.

Front

What type of organisms have specialized cells?

Back

Multicellular organisms.

Front

What is a niche in ecology?

Back

The role an organism plays in its environment, including its habitat, resource use, and interactions with other organisms.

Front

What is the genetic material found in the nucleus of a cell?

Back

DNA (Deoxyribonucleic Acid).

Front

What structure in the cell contains DNA and regulates the cell's activities?

Back

Nucleus.

Front

What is the function of the mitochondria in a cell?

Back

Mitochondria are the powerhouses of the cell, generating ATP through cellular respiration.

Front

Define prokaryotic cells.

Back

Prokaryotic cells are simple, single-celled organisms without a nucleus or membrane-bound organelles, such as bacteria.

Front

What is the primary function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment.

Front

What is the difference between biotic and abiotic factors?

Back

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