• Predator
• Prey

• Adaptation

Why does..... an increase in predators lead to decrease in prey?

• predators eat too many prey

• predators scare prey away

• predators leads to decrease in producers

Temperature, light, air, water, and soil are all ___________ parts of the environment.

• biotic
• abiotic
• dead
• scavenged

On a Range of Tolerance graph, what is the zone called where only a few organisms are?

• Zone of Intolerance
• Optimum Zone
• Zone of Physiological Stress
• Population Zone

The amount of oxygen in a fish tank is a _______ that affects the number of fish that can live in the tank

• Tolerance zone

• Limiting factor

What is the term for each step in the transfer of energy and matter within a biological community?

• energy path
• food web
• trophic level
• food pyramid

What does a food web represent?

• All connections of energy flow throughout all organisms in a habitat.
• The specific ways that mutualism is carried out.
• A single pathway or energy flow between organisms. 
• How carnivores get their food. 

Organisms that breaks down and absorbs nutrients from dead organisms 

• consumer
• trophic level
• decomposer
• species

Producers obtain their energy by

• the process of hunting for prey

• the process of eating plants

• the process of photosynthesis to make their own food from sunlight

• the process of breaking down once living things

The job of decomposers in an ecosystem is to

• break down once living things from all levels of the ecosystem to recycle nutrients back to producers

• break down only top level consumers to recycle nutrients

• break down only producers to recycle nutrients

• give energy to all levels of the ecosystem
