| decomposers | an organism that breaks down wastes and remains of other organisms and add nutrients to the soil |
| carnivore | an animal that eats other animals |
| herbivores | an animal that eats plants |
| omnivores | an animal that eats both plants and animals |
| food chains | the transfer of energy and matter from one living thing to another by eating and being eaten |
| food web | a system of overlapping food chains in which energy and matter flow through many branches |
| microorganism | a living thing too small to be seen without a microscope |
| symbiosis | the relationship between two different living things that live together and depend on each other |
| What is the main source of energy for most ecosystems? | sunlight |
| How does energy flow between organisms | animals get energy by eating or consuming plants or animals. Energy flows from sun, to plants (producers), to animals (consumers) and to decomposers |
| primary consumers | Primary producers provide usable energy for living organisms. PRIMARY CONSUMERS (herbivores) eat primary producers . |
| Secondary consumers | SECONDARY CONSUMERS (carnivores) eat the primary consumers |
| adaptation | a body part or behavior that helps an animal meet its needs in its environment |
| Climate | the average temperature and rainfall in an area over many years |
| what gas is released in the air by plants | oxygen |
| How does camouflage help an animal | it helps it blend in with its surroundings |
| photosynthesis | the process that plants use to make food |
| population | all the members of one species that live within an area of an ecosystem |
| community | the different populations that interact with each other in the same area form. |
| competition | two organisms of the same species Organisms of different species |
| What is the primary source of matter and energy in most food chains? | plants |
| What show a flow of energy from producer to consumer? | food chain |
| Name a producer | plant |
| Animals use special behaviors to ____________ their territory | defend |
| trait | adaptation |
| organisms | producers, consumers, decomposers |
| What is on the bottom of a food chain? | producers |
| What is the difference between a primary consumer and a secondary consumer? | A primary consumer eats plants that make food and a secondary consumer eats primary consumers. |
| Two animals live in the same environment and eat the same food, what exists between them? How do they survive? | Competition...eating a variety of food, nocturnal |
| individual | a single type of organism |
| What is an example of a decomposer? | fungi, worms, bacteria |
| coral reef | skeletons of tiny sea animals that pile up |
| fertilization | Combining of a sperm cell and an egg cell |
| rainforest | an ecosystem that has large amounts of precipitation and thick plant growth |
| understory | an area of a rain forest below the canopy |
| desert | an ecosystem that receives very little precipitation |
| seed dispersal | the process of scattering plant seeds |
| canopy | the top level of a rainforest |
