Ecosystem A community of living and nonliving things in their natural environment
Living Element
Part of an ecosystem that requires energy to survive has basic needs that must be met
Nonliving Element
Part of an ecosystem that does not require energy to survive and does not have basic needs like food and water
Producer An organism that used sunlight to make its own food for energy
Consumer An organism that gets energy from eating other organisms
Organism A living thing
Decomposer An organism that gets energy from eating dead organisms, nonliving materials, or waste
Food Chain The path of food energy from one organism to another in an ecosystem
Food Web A connection of food chains with many food energy paths in an ecosystem
Photosynthesis
The process where plants use sunlight, water, and carbon dioxide to produce sugar and release oxygen
Respiration A process by which animals use oxygen and food to make energy and carbon dioxide
Population All the living things that belong that belong to the same group and live in the same area
Cycle A recurrent series of events or processes in plants and animals
Overpopulation Can create too much of one species, which exhausts our food supply. Can destroy habitats
Grazing To eat small portions of food throughout the day
Flow Ecosystems maintain themselves by cycling energy and nutrients obtained from external sources.
Carbon Cycle
The movement of carbon on Earth by the processes of respiration and photosynthesis
Oxygen A gas produced by plants during photosynthesis that animals use for respiration
Carbon Dioxide
A gas produced by animals during respiration that plants use to make food, water, and oxygen
