Each plant or animals has different structures that serve different functions in growth survival, and reproduction. Humans and other organisms have senses that help them detect internal and external cues. Plants and animals have life cycles that include being born, developing into adults, reproducing, and eventually dying. Some characteristics of an organism are inherited others result from interaction with the environment. All animals depend on plants.
Some animals eat plants and some animals eat animals that eat plants.
An organism's behavior is related to the organism's environment. When the environment changes, some organisms survive, others die or move away. All organisms cause change in the environment where they live. Humans depend on their natural and constructed environments. Plan and conduct a simple investigation.
