BIO-220 Topic 2 DQ 2
Select an example of a global biome and an example of an ecosystem found in that biome (grassland, forest, desert). What kind of animals and plants would you expect to make up that ecosystem? Provide one symbiotic relationship example within your selected ecosystem (such as mutualism, commensalism, and predatory prey).
There are different types of relationships.
- Mutualism: Individuals of both species benefit (i.e., ox-pecker, a type of bird that eats parasites from rhinoceros)
- Parasitism: Individuals of one species feed on individuals of the other species, causing them harm without necessarily killing them (e.g., tape worms, ticks, bot flies). This is also sometimes grouped with predation because both are consumed.
- Predation: Individuals of one species kill and consume individuals of the other species.
- Commensalism: Individuals of one species benefit, but the other is not hurt or harmed (e.g., a bird nesting in a tree doesn’t hurt the tree; a scavenger eats the left-overs that have been abandoned by a predator).
- Competition: Individuals of both species use either the same food, water, or shelter type, so they are competing with each other like in a sports game.
