Biodiversity and Ecosystem Concepts

Flashcards covering key concepts related to biodiversity and ecosystems.

What does biodiversity in an ecosystem include?

Genetic, species, and habitat diversity.

What is species richness?

The number of different species found in an ecosystem.

What is genetic diversity?

The variation of genotypes and phenotypes among individual organisms of the same species.

What is species diversity?

The visible differences and variety among different organisms.

What is habitat diversity?

The variety of different habitats within a biome.

What is the correct sequence from organism to biosphere?

Organism-Population-Community-Ecosystem-Biome-Biosphere.

What is species evenness?

The relative abundance of different species in a habitat.

What is natural selection?

A mechanism of evolution where organisms better adapted to their environment survive and reproduce.

What is a gene pool?

The complete set of genes, including alleles, within a reproducing population.

How does population diversity affect its response to environmental stressors?

A more diverse population can better respond to environmental stressors.

What happens to specialist species with habitat loss?

A loss of habitats leads to a loss of specialist species, which is followed by a loss of generalist species.

How do ecosystems with a larger number of species respond to disruptions?

They are more likely to recover from disruptions.

What is the anthropocentric worldview?

A worldview that emphasizes human focus and economic purposes.

What is the biocentric worldview?

A worldview that considers both human interests and the needs of nature.

What is the ecocentric worldview?
