When an organism hunts, captures, and kills another organism for food
What is Predation?
The name for organisms that make their own food.
What are autotrophs?
Population growth that occurs when there are unlimited resources in an environment.
What is Exponential Growth?
The main molecule in the Carbon Cycle
What is Carbon Dioxide?
This is how an organism interacts with its environment.

A species of barnacle castrates its host, depriving it of the ability to reproduce and diverting its energy to care for the barnacle. This is an example of this type of interaction.
What is Parasitism?
The amount of energy that is passed on from one trophic level to the next.
What is 10%?
Pollution, Natural Disasters, Habitat Destruction, and Weather Patterns are examples of this type of limiting factor.
What are Density-Independent limiting factors?
Agricultural fields are frequently abandoned when the landowner stops farming. If left alone, these abandoned fields gradually change back to forest over many years. This is an example of this type of succession.
What is Secondary Succession?
These organisms are not native to an area. They cause harm to the ecosystem and experience a large increase in population.
What are Invasive Species?
Spider crabs live in shallow areas of the ocean floor, and greenish-brown algae lives on the crabs' backs, making the crabs blend in with their environment, and unnoticeable to predators. This is an example of which type of ecological relationship?
Which organism would have more energy available to it? A primary consumer or a tertiary consumer?
Primary Consumer
Competition, Predation Rates, Disease, and Hunting are examples of this type of limiting factor.
What are Density Dependent limiting factors?
An undersea eruption in 1963 formed the island Surtsey, off the coast of Iceland . By 2008, about 30 plant species had been established. This is an example of this type of succession.
What is Primary Succession?
List 3 biotic factors in an ecosystem.
Amount of plants, predators, prey, disease, parasites, decomposers, mates, etc.
What is a Commensalism?
This is what happens to the 90% of energy not passed on to the next trophic level.
What is used in metabolism or lost as heat?
The four factors that affect populations
What are Birth, Death, Immigration, Emigration?
Process of turning unusable atmospheric nitrogen into a usable form in the soil.
What is Nitrogen Fixation?
List 4 abiotic factors in an ecosystem.
