- Ecology
- a study of how organisms interact with each other and their enviorment. this includes both libing and non-living things
- Herbivore
- An animal that eats only plants or plant material.
- Biodiversity
- the variation of plant and animal life in a given habitat, ecosystem, biome, or for the emtire Earth
- Tundra biome
- Artic grasslands north of the taiga Very few plants and animals exist here.
- Abiotic
- non-living parts of an ecosystem.
- grassland Biome
- Wide open fields of grass. Rainfall varies. Found on all continents.
- Deforestation
- the clearing and removal of trees and undergrowth
- extinct
- the entire species has died off. it is gone forever
- threatened
- Species in danger of becoming endangered.
- carnivore
- an animal that eats other consumers
- food web
- a diagram of all of the food chains in and ecosystem. there is a lot of overlapping that occurs in the web ("who eats who?")
- desert Biome
- can be hot or cold, but is always dry. contains few plants & animals
- omnivore
- Animals that eat both plants and animals.
- Amazon rain forest
- the largest rain forest in the world, located in South America (1.5 million square miles
- Biomes
- ecosystems that cover large areas
- environment
- all living and non living thing in the place which a organism lives
- biotic
- all of the living things in an environemnt
- Understory layer
- Just above the floor. Tree trunks, saplings, small ground plants, and vines grow there Bees, snakes, frogs, and leopards live there.
- rain forest
- forests along the equator that remain hot and hunid all year long.
- Deciduous forest Biome
- a forest biome with trees that lose their leaves n the fall. rainfall is moderate.
- endangered
- speceis in danger of becoming extinct
- food chain
- a pathway that shows the eating of food from the producers (plants) to the next comsumer, to the next consumer, to the next consumer, and so on until the top of the food chain is reached (grass uses photosynthesis to change sunlight into food energy, rabbit eats the grass, fox eats the rabbit, eagle eats the fox)
- exponential growth
- in a population, growth that starts out slow, and increases faster, and faster, and faster
- forest floor
- The lowest layer of a rainforest. Decaying fallen trees and fruit put nutrients back into the soil. Tapirs, termites, and scorpions live there.
- canopy layer
- the "green blanket" of treetops that keeps most of the sunlight from reaching the forest floor. this layer comtains the most animals of any layer. toucans, parrots, sloths, and monkeys live here
- species
- All the members of a population that have the same general charecteristics and can mate, producing offspring of the same kind. For example redheaded woodpeckers.
- population
- All the organisms that live together in an ecosystem. Made up of many different species.
- habitat
- The place or enviorment where a plant or animal naturally or normally lives and grows.
- Autotroph
- plants that can make food by photosynthesis (using the energy of sunlight to convert water, minerals, ect., into food for animals
- consumer
- organisms that can't make their own food,so it eats "producers" or other consumers that eat producers.
- emergent layer
- tall trees (200+feet) that rise above the canopy scattered throughout the rainforest. birds of paradise (flower), eagles, macaws live here
- Ecosystem
- all the living things in a given area that funtion together
- Taiga Biome
- Conferous (evergreen) forests have long, cold winters .The trees have needles instead of broad leaves.
- organism
- a living being; one celled to extremley conplex
- producer
- plants that are able to make food for themselves by changing energy from the sun (sunlight) into food energy
- community
- (ecology) a group of interdependent organisms inhabiting the same region and interacting with each other
