Science-Food Chains

 In science, we are in the midst of our biology unit. Our focus will be on food chains, food webs, photosynthesis, biomes, adaptations, and the interrelationship between plants, humans, and animals.We will cover the following:

* Give examples of how inherited characteristics may change over time to adaptations to changes in the environment that enable organisms to survive.

* Give examples of how changes in the environment have caused some plants and animals to die or move to new locations.

* Describe how organisms meet some of their needs by using behaviors in response to information received from the environment.

* Recognize that some behaviors are inherited and some are learned.

* Give examples of how organisms can cause changes in their environment to ensure survival.

* Describe photosynthesis.

* Describe how energy is transferred within a food chain.

* Describe how energy is transferred within a food web.

* Explain the roles and relationships among producers, consumers, and decomposers in the process of energy transfer in a food web.

*Explain how dead plants and animals are broken down by other living organisms.
