Biology of how different species relate to each other (persistence, resilience, structure and dynamic)

One species wins the competition, the inferior species has to die or change

When an animal species grazes on shrubs, shrubs do not usually die

The most common interaction between species, interaction between host and parasite

Single celled microorganisms that give us diseases, also a parasite, most commonly studied

A community change that is more or less predictable, predictable meaning the growth pattern of which species come first and those that follow

The process starts from a blank slate, where there is no life at all (lava or glacial break down)

The process starts after some type of disturbance (wild fire, bulldozers, clear cutting)

r selection is fast reproducing, but has a high mortality rate and is usually the first to grow in an environment; K selection is slow at reproducing, but majority survive and joins an environment after it has evolved a bit

All living organisms that interact together in a place, combined with all the nonliving characteristics of that place

How organisms interact with each other and their environment

Autotrophic: species that feed themselves (plants) Heterotrophic: species that feed on other species (people) Detritrivores: those that feed off of dead things

A linear composition of who eats whom:

grass à grasshopper à meadow lark à hawk

The change in a food web by either gaining or losing an animal

The water cycle: rain, precipitation, runoff and how this affects groundwater aquifers that supply most of the human population with water

Shows major carbon reservoirs and pathways of carbon movement on the planet

Nitrogen Cycle

Shows major pathways and forms of nitrogen (we generate lots of poop)
