EOG Study Guide

ecology

the study of how living things interact with each other and their environment

ecosystems

consists of abiotic and biotic factors in an area

ecologists

are the scientists who study the interactions between biotic and abiotic factors

biotic

factors of the living parts of an ecosystem

abiotic

factors of the nonliving parts of an ecosystem

humans, animals, trees, plants, bacteria, fungi

five biotic factors

sunlight, soil, water, air, climat

five abiotic factors

deciduous forests, desert, grassland, tundra, rainforest

list six major ecosystems or biomes

deciduous forest

an ecosystem that loses leaves each Fall

rainforests

an ecosystem with very warm temperatures and heavy rainfall

rainforests

an ecosystem with thousands of different organisms

grasslands, savannah

an ecosytem with elephants, giraffes and zebras

pond

a freshwater ecosystem with cattails, water lilies, snails, insects, frogs, turtles, and fish

tundra

an ecosystem with very cold temperatures, polar bears, artic foxes, permafrost, and treeless

desert

an ecosystem that is sandy, rocky, very little precipitation, with cacti

water

needed for all organisms to live

producer

organisms that use energy from the sun to make their food

photosynthesis

the process to make their own food

plants

are most producers

algae, seaweed

producer of the ocean

consumers

organisms that get energy by eating other organisms

herbivores, carnivores, omnivores

three types of consumers

herbivore

a consumer that eats only plants

carnivore

a consumer that eats only other animals

omnivore

a consumer that eats plants and animals

decomposers

organisms that get energy by breaking down nutrients in dead organisms

omnivores

pigs, bears, raccoons are examples

herbivores

zebras, elephants, and giraffes are examples

decomposers

fungi and bacteria are examples

omnivores

humans are examples

producers

grasses, shrubs and trees are examples

carnivores

sharks, lions, wolves, hawks are examples

scavengers

carnivores that eat dead animals

decomposers

termites and earthworms are examples

scavengers

vultures, croes, hyenas are examples

decomposers

organisms that return nutrients back to the soil

population

a group of organisms of the same species living in the same place

community

all the population that live in the same area

community

the populations of frogs, mosquitoes, cattails all make up a pond

deer, wolves, ticks

name three populations of the deciduous forest

habitat

the place where an animal lives

true

True or False - A forest ecosystem can support the life of various organisms

niche

an organism's lifestyle

night, day

part of an owl's niche is to hunt when and while other animals hunt when

food, shelter

when organisms occupy the same niche, they compete for what resourses

decrease or die

the weaker population may

sunlight, water, soil, climate, air

list five abiotic factors of an ecosystem

sun

main source of energy for all living things on earth

location, nearness to water

affects temperature of an area

environments

where organisms with special adaptiation can live

cactus, camel, arctic fox

two examples of organisms with special adaptations

predator

an organism that eats other organisms in order to live

predator

the hunter

prey

organism eaten

prey

the hunted

camouflage, talons

two adaptations that help predators or prey

parasite

organisms that live in other organisms to get energy

host

the organism that is fed off of

loses energy

why is the hosted harmed by the parasite

parasites

fleas, ticks, leeches, tapeworms, and mistletoe

food chain

shows the path of energy from one organism to the next

food web

several connected food chains

one organsim

food webs show how organisms don't just eat

pollution

an unwanted change in the environment

cut down trees, pollute

list ways that humans change the environment

water

the most important nutrient on earth

water

without this, life on earth would be impossible

carbon

all living things ae made of this, which moves through the environment and living things in a continuous cycle.

carbon

photosynthesis and respiration are part of this cycle

nitrogen

bacteria and decomposers convert this gas into a form organisms can use to build proteins and perform bodily functions

rainforest

monkeys, toucans, and parrots make up what ecosystem

biome

an ecosystem with its own climate, soil, plants, and animals

endangered

an animal that may become extinct

extinct

animals that no longer exist

decomposer

the last link of all food chains

producer

first link of all food chains

consumer

the second link of all food chains

habitat loss, reduction

likely consequence of cutting down rain forest

decrease in population

may decrease the sunlight in an ecosystem

competition

this reduces when different organisms eat various types of organisms within the ecosystem
