Abiotic factors that living things need to use to survive: Food (ENERGY) Water Air

How do living things get their food (ENERGY)? Some living things need to CONSUME (eat) other living things to survive. They have internal and external structures that let them do this. Any living thing that has structures allowing them to consume other living things is called an…

Animal/ Consumer

How do living things get their food (ENERGY)? Some living things do NOT have internal and external structures that let them consume (eat) other living things. Any living thing that has structures allowing them to make their own energy (food) is called a…

Plant/ Producer

How else are animal and plant structures the same and how are they different?

Animals and plants both need water, but they get water in slightly different ways.

Animals and plants both need air, but they get air in slightly different ways.

The water, air, and food (energy) that plants and animals use are all made up of one or more of these elements:
