Interactions

Ecology

organism
Eat producers
Herbivore
anything that can limit the size of a population, including living and nonliving features of an ecosystem, such as predators or drought

Give the definition for Habitat

Predator
animal that hunts and kills other animals for food.
What are the three types of symbiosis? Using positive, negative, or neutral symbols, describe what each organism gets out of the relationship for each interaction.
a.mutualism ++ both species benefit from the interaction
b.commensalism+0 one species benefits while the other is not affected.
c.parasitism +0 one species benefits while the other one is harmed.
Ecosystem/Biome
large geographic areas with similar climates and ecosystems, Includes: Tundra, Desert, Tropical Rainforest, Temperate Rainforest, Grassland, Arctic Tundra, Temperate Deciduous Forest
an animal that is hunted and caught for food. Prey is a consumer, it may be a herbivore, omnivore, or carnivore.

List some limiting factors that might limit the size of a population within its environment
Resources such as water, air, shelter, and food; competition with other organisms for the same resource. natural disasters, accidents & disease
