CRAAP

Currency- relevance- authority- accuracy- purpose

Primary succesion

Pioneer species, climax community, everything is lost

Climate

The weather conditions prevailing in an area in general over a long period

Climate zones

Tundra, desert, rain forest, deciduos forest

Affect on climate

Latitude, altitude, ocean currents, marine vs continental

Rainfall factors

Latitude, mountain- orographic precipitation

Latitude lines

Go from 0 degrees to 90 degrees both north and south of the equator

Three main climate zones

Polar zone, Tropic zone, temperate zone

What defines each climate zone

The variation in temperature or precipitation

Albedo

The lower the albedo, the more radiation from the sun that gets absorbed by the planet

Greenhouse affect

Gases in the atmosphere, such as co2, trap heat just like the glass roof of a greenhouse

Distance to ocean

Coastal areas are cooler and wetter than inland areas

Mountain ranges

Mountain affect climate by blocking wind and recieving more rainfall than low-lying areas

Commensalism

One organism benefits from the interaction, while the other is not hurt or harmed

Green algae

Grows in fur of sloth to give them camouflage

Mutualism

Both organisms benefit

Parasitsm

One organism benefits, while the other dies or gets hurt

Competition

Fight for resources between two organisms

Predator

Predator hunts prey for food

Omnivores

Animals that eat both plants and animals

Carnivores

Animals that eat meat are

Herbivores

Animals that eat plants

Plants

can be called autotrophs or producers

Foodweb

Starts/always needs SUN

Tropical rainforests

Heavy rain and hot

Population

Group of the same species

Community

Group of different species

Grassland

a large ecosystem where grass and grass-like plants, not trees

Deciduous forest

a biome characterized by broadleaf trees that lose their leaves seasonally, adapting to cold winters and warm, wet summers

Tundra

a biome characterized by cold, treeless plains and short growing seasons found in high latitudes and altitudes

Rainforest

an ecosystem of dense, tall trees and moisture-dependent vegetation that receives high amounts of rainfall.

Independent variable

1. a variable (often denoted by x ) whose variation does not depend on that of another. You can control

Dependent variable

a factor measured in an experiment that changes in response to the independent variable. CANT CONTROL

Controlled group

is a set of subjects in an experiment that do not receive the specific treatment or intervention being tested, serving as a baseline for comparison. NO CHANGES
