What is exponential growth in a population?

Back

Exponential growth occurs when individuals in a population reproduce at a constant rate, leading to a rapid increase in population size.

Front

What happens to a population when the death rate becomes higher than the birthrate?

Back

The population decreases as more individuals die than are born.

Front

What are some threats to biodiversity?

Back

Threats to biodiversity include habitat fragmentation, invasive species, and biological magnification of toxic compounds.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate refers to the long-term average of temperature and precipitation in a region.

Front

What is mutualism?

Back

Mutualism is a symbiotic relationship in which both species benefit from the interaction.

Front

What is habitat fragmentation?

Back

Habitat fragmentation is the process where large habitats are broken into smaller, isolated patches, negatively impacting species that require larger territories.

Front

What are invasive species?

Back

Invasive species are non-native organisms that spread widely in a new environment, often causing harm to native species and ecosystems.

Front

What is biological magnification?

Back

Biological magnification is the process where toxic substances accumulate in higher concentrations as they move up the food chain.

Front

What is the role of species preservation?

Back

Species preservation involves protecting endangered species and their habitats to maintain biodiversity and ecosystem health.

Front

What is the definition of a population in ecology?

Back

A population is a group of individuals of the same species living in a specific area at the same time.
