• a limiting factor

• carrying capacity

• biodiversity

What provides most of the energy in an ecosystem?

• Keystone species

• Carnivores

Describe the interaction between plants and animals

• Plants provide humans with carbon dioxide for respiration

• no change in ecosystem

• species would become prey for ALL organisms

• species would become the predator for the ecosystem

• non-native species could perhaps cause problems or may become an important asset to the ecosystem

What type of population growth is represented?

• exponential

• logistic growth

• Density dependent

• carrying capacity growth

Which action would increase the amount of oxygen in a fish tank?

• Adding more fish

• Adding more plants

• Placing food in the tank

• Placing a water heater in the tank

What type of respiration requires oxygen?

• Aerobic
