Eco Ch5.1-5.3 (LitE)

occurs when members of 2 or more species interact to gain access to the same limited resources such as food, water, light, and space.

occurs when a member of one species (predator) feeds directly on all or part of a member of another species (prey).

occurs when one organism (parasite) feeds on another organism (host), usually by living on or in the host.

the interaction that benefits both species by providing each with food, shelter, or some other resource.

the interaction that benefits one species but has little or no effect on the other.

occurs when species competing for similar scarce resources evolve specialized traits that allow them to share resources by using parts of them, using them at different times, or using them in different ways.

an adaptation that allows predators and/or prey to hide in plain sight.

using poisons to paralyze prey or to deter predators.

brightly colored advertising that helps experienced predators/prey to recognize and avoid them.

where nonpoisonous organisms gain protection by looking like poisonous ones.

when populations of 2 different species interact in such a way over a long period of time develop changes in the gene pool of the other. It allows both sides to become more competitive.

a way to navigate and locate prey using pulses of high-frequency and high-intensity sound which bounces off objects, and the returning echoes tell them where their prey is located.

vast armies of bacteria in the digestive system of animals help to break down the animals' food.

plants like orchids and bromeliads which attach themselves to the trunks or branches of large trees in tropical and subtropical forests. An example of commensalism: the plant gets sunlight, water, and air and the tree is not harmed nor benefits.

a group of interbreeding individuals of the same species.
