What is a producer?
Most ecosystems ultimately obtain their energy from this source.
What is the Sun?
A relationship in which both species benefit is called this.
What is mutualism?
This type of succession begins in an area where there is no soil
What is primary succession?
What term describes the role an organism plays in its ecosystem
What is Niche

What is a primary consumer?
Plants use this process to convert light energy into chemical energy stored in glucose
What is photosynthesis?
A bird eats insects living on the back of a large mammal. The bird gets food, while the mammal benefits from having parasites removed. This is an example of this type of relationship.
What is mutualism?

What is they help break down rock and contribute to soil formation?
Three species of warblers live in the same tree. They will on different sections of the tree. What ecological strategy allow them to reduce competition
What is resource partitioning?
A food web contains many interconnected food chains. Arrows in a food web point in the direction of this.
What is energy flow?
Organisms use energy from food for movement, growth, reproduction, and maintaining body functions. Some of that energy is eventually released as this form of energy
What is heat?
A tape absorbs nutrients from the mammal's digestive system. The tapeworm benefits while the mammal is harmed. What type of relationship is?

Two male elk compete by locking antlers during mating season
What is intraspecific competition?
What are two examples of primary succession?
What are glaciers and volcanoes?
A species can survive a wide range of temperatures when no other species are present. When a competing species is introduced, however, it can only survive in a smaller temperature range. What concept does this demonstrate?
