Food Chains & Food Webs Notes
Living things depend on ecosystems for survival. An ecosystem is an area that is made up of living and nonliving things. Living things (biotic) in an ecosystem include animals, plants, fungi, and bacteria. Nonliving things (abiotic) can include water, rocks, and soil.
The Sun provides the initial energy for almost every ecosystem on Earth.
Plants are known as producers. Producers use sunlight to make (or produce) their food using carbon dioxide and water. Producers are at the beginning of every food chain. ALL life in an ecosystem depends on producers to capture and use the Sun’s energy so that it may be passed on to other organisms.
Other than plants, ALL other organisms must eat to get their energy. The animals in a community are called consumers because they eat (or consume) plants or animals.
Energy passes through communities in food chains. Food chains show the ways in which organisms interact with one another and the flow of energy/nutrients. An example food chain could be blackberriesrobinbobcat. The direction in which the arrow points shows the organism that receives the energy. The robin gets energy from the blackberries, and the bobcat gets energy from the robin.
Food chains are organized into levels. Within the consumer levels, there are also omnivores that eat both plants and animals. 1) Base level: producers 2) First-level (primary) consumers: herbivores (animals that eat plants) eat producers 3) Second-level (secondary) consumers: carnivores (animals that eat meat) eat herbivores 4) Third-level (tertiary) consumers eat carnivores.
Decomposers, like mushrooms, worms, and bacteria, are consumers that break down dead organisms. Whatever the decomposers don’t use as food is cycled back into the soil, allowing decomposers to connect both ends of a food chain.
Predators are consumers (animals) that hunt and kill other animals. They must eat other animals to get the energy they need to survive. Predators help limit the size of prey populations.
Scavengers are animals that feed on the remains of dead animals that they did not hunt or kill. Scavengers help remove dead organisms from an ecosystem.
Food webs show the relationships between many different food chains within an ecosystem. A food web shows how organisms may be part of several food chains at the same time. Food chains overlap to create a food web.
Energy pyramids show how much energy passes from one level of a food chain to the next. In most ecosystems, there are many more producers than consumers. Producers use about 90% of the energy they make during photosynthesis, so only about 10% of the energy is stored in the plant tissue. When a first-level consumer eats a plant, the animal uses 90% of that energy and stores 10%. Then, a second-level consumer eats the animal, uses 90% of that energy, and stores the remaining 10%. ONLY 10% OF THE ENERGY AT ANY FOOD CHAIN LEVEL IS PASSED ON TO THE NEXT HIGHER LEVEL.
