7.5 - 4 Dynamic Nature of Ecosystems

Population

• The ability of an organism, population, community, or ecosystem to persist in the face of stressful or changing conditions

• A group of organisms that are similar to one another and can mate to produce offspring

• Characterized by constant change, activity, or progress

• A group of interacting individuals of the same species located in the same area

The attached picture is an example of what natural process?

• Ecological succession

• Evolution of species

• Environmental growth and development

• Species variation

An algal bloom affects its environment in all of the following ways EXCEPT –

• It decreases the amount of oxygen in the water.

• It filters the water to make it healthier for wildlife.

• It blocks sunlight so plants cannot perform photosynthesis.

• It produces harmful toxins.
