Ecological Relationships Review II

Some organisms use __________ to help protect them from being preyed upon by other animals.

Ambush predation allows the animal to conserve __________, an excellent survival skill in a world where hunting may be difficult.

Unlike ambush predators who generally __________ for their potential prey to come within striking distance before consuming it, pursuit predators give chase, meaning that they essentially pursuit or chase after their prey.

Flounders are another fish that use __________ to catch their meals. These flat fish are found throughout many oceans in the world, but you may have to look hard to find them. By snuggling just under the top layer of ocean floor sand or pebbles, the flounder is nearly totally invisible.

We know that predators are secondary, tertiary or even __________ consumers that eat other organisms to obtain nutrients.

Certain predators choose to pursue prey primarily in a group; these animals are known as __________ or group pursuers.

Other species choose to hunt alone. Examples of __________ are bobcats, polar bears, leopards, and pumas. Solitary carnivores don't hunt prey together, defend together, or even raise offspring together.

The __________ ends either when the predator successfully catches up and tackles the prey, or when the predator abandons the attempt after the prey outruns it and escapes.

In __________, organisms interact with each other to obtain a resource, like two birds fighting over a fish.

One type of __________ is exploitative competition, when one group or individual uses so much of a resource that others cannot use it. For example, a growing wolf population could eat the whole food supply of other carnivores.

Intraspecific competition occurs when individuals of the same species compete for a limited resource. True/False

Inter-specific competition occurs when different species compete for the same resources. True/False

__________ occurs when different species compete for the same resources but one species consumes the majority of the limited resource.

__________ competition occurs when two individuals that do not directly compete for resources affect each other indirectly by being prey for the same predator.

Which of these is NOT an example of inter-specific competition?

Which of these are conditions required for two species to compete?

Which of these best describes interspecific competition?

When a pine tree grows tall and blocks sunlight to another pine tree it is _______ competition.

Environmental change can cause apparent competition to occur within an ecosystem. True/False

A decrease in one prey can also affect the population of another prey within the same ecosystem, as now they will be heavily targeted by the predator. True/False

Which of these external factors can affect ecological competition? (Select all that are correct):

Which of these is an example of direct competition.
