| sun | all living things depend on energy from the____ |
| producers | make their own food |
| consumers | living things that cannot make their own food |
| photosynthesis | the process of how living things produce their own food |
| relationships | producers and oonsumers depend on each in complex_______ |
| food chain | this shows how one living thing depends on another living thing and how energy flows |
| first | this is the link on the food chain where the producers are |
| primary consumers | organisms that eat producers |
| herbivores | this is another name for a primary consumer |
| special body parts | herbivores have these to help them break apart tough plants |
| energy | primary consumers eat producers and get ________ that came from the sun |
| secondary consumers | these animals feed on the herbivores |
| carnivores | meat eaters |
| tertiary consumers | these are animals that eat other carnivores |
| omnivores | animals that eat both plants and animals |
| predators | animals that hunt and eat other animals |
| prey | the animals that are hunted by the predator |
| ecosystem | producers, predators, prey, air, water, and other parts of an area are called an _________ |
| scavengers | these carnivores feed mainly on dead animals |
| decomposers | the last link in a food chain that make sure that none of the energy in a food chain is wasted |
| break down | many decomposers do this to dead plant material and the waste and dead bodies of animals |
| recycle | decomposers do this to nutrients |
| trash | without decomposers, Earth would be covered with this |
| food web | many food chains that are linked together |
| energy pyramid | this describes how energy is lost as it passes from one part of the food chain to the next |
| fraction | when a herbivore eats plants only a ______ of the energy from the plants is used by the animal to grow |
| more | ecosystems need more producers than consumers in a food chain |
| five | a food chain cannot have more than this many links so the animals at the end have enough food to stay alive |
| parasites | these are special types of consumers who use another living thing as a food source like a tapeworm living inside a mammal |
| host | this is the living thing that a parasite feeds on |
| adaptations | special body parts or behaviors that help animals find what they need to survive |
| changes | things like diseases, oil spills, pesticides that occur in an ecosystem that harm food chains and food webs |
| global warming | this change in temperature can affect organism in a food web |
| invasive species | when people bring a new non-native species into an environment |
