Biology chapter 3

what do chemical processes include

• series of steps in which organisms transfer energy

• includes the formation of clouds, precipitation and the flow of running water

• includes the formation of heat

• includes processes in which an organism breaks down energy

what is ecology?

• the study of how humans interact between each other

• the study of interactions between organisms and their environment

• each step in a food chain or food web

• elements that pass from one organism to another among parts of the biosphere through closed loops

what consists in a biosphere

• all living things on Earth

• all living things on earth except abiotic factors

• a population

• an individual, population, and community

• the biome

what are primary producers

• the secondary producers

• carnivores

• the first producers of energy-rich compounds that are later used by other organisms

• carnivores, herbivore, omnivore, scavengers, decomposers

• plants and animals

what are food chains

• each step in a food chain

• a series of steps in which organisms transfer energy by eating and being eaten

• processes that deal with food chains

• a series of food webs in which organisms can transfer energy easily

what is a trophic level

• elements that pass from one organism to another

• the level in which primary producers are

• another word for pyramids of mass

• each step in a food chain or food web

what are biochemical cycles

• processes that deal with land

• cycles that include the transition of organisms through the biosphere

• elements that pass from one organism to another among parts of the biosphere through closed loops

• the repetition of biochemical processes

what are geological processes

• includes processes that deal with land such as volcanic eruption, erosion, and weathering

• includes processes that deal with non-living things

• deals with the different geographical evolutions

• energy flows through an ecosystem

geological processes deal with..

• money and trade

• land - volcanic eruption, erosion, and weathering

• non- living factors - heat and temperature

• biomes

how is economics and ecology linked

• economics is concerned with human interactions based on money and trade; in both, organisms and humans are trying to meet their needs

• economics are concerned with human links and both, include the needs and wants of organisms

• they both are talking about abiotic and biotic factors

• they both are in the biosphere and all of the organisms interact with eachother
