energy pyramid and food webs by: emerson hebert

Energy Pyramid: An energy pyramid is a model that shows the flow of energy from one trophic level to the next in an ecosystem. The bottom and largest level of the pyramid is the producers and contains the largest amount of energy. The 10% rule is how energy gets transferred. The producers start with 10,000 kcals, then divide by 10 each time.

Food chain: a series of organisms each dependent on the next as a food source. Each food chain is a pathway that energy and nutrients can follow through the ecosystem. The arrows represent the transfer of energy or point to what the organism eats. One example from the picture is a mouse which is a secondary consumer, then eats a grasshopper, or primary consumer, which finally eats grass which is a producer.

Food Web: a food web is a system of food chains.

Trophic Levels: Each of several levels in an ecosystem, that show where animals fall in an ecosystem. There are 4 main trophic levels. At the bottom is a producer, then the primary consumer, the secondary consumer, the tertiary consumer, and finally the apex. An apex consumer does not have a predator within the animals in the levels.

Photosynthesis: Photosynthesis is the process in which green plants and other organisms use sunlight, carbon dioxide, and water to create food within them. The products of this process are oxygen and sugar. In photosynthesis, an energy transfer occurs. Photosynthesis allows plants to transform solar energy into chemical energy necessary for their growth.

producers: a producer is any type of green plant. green plants make their food by taking sunlight and using the energy to create sugar. the plants use the sugar, or glucose, to make many things. such as wood, leaves, roots, and bark.

Primary Consumers: Primary consumers make up the second trophic level. Primary consumers are also herbivores. A herbivore is an animal that only eats plants. For example, a rabbit is a primary consumer.

Secondary consumers: Secondary consumers are the 3rd trophic level. Secondary consumers are mostly carnivores, that feed on primary consumers, or herbivores. They are heterotrophs which means they cannot make their own food. They are carnivores and omnivores, which means they eat plants and animals.

Tertiary consumer: Tertiary consumers eat secondary consumers. They are normally the larger predators. These consumers usually exist at or towards the top of the food chain. For example owls, an owl who eats a snake is a tertiary consumer.

Decomposers: A decomposer is an organism that decomposes organic material. Most decomposers are microscopic organisms, including protozoa and bacteria. Decomposers occupy the last trophic level or the top of the ecological pyramid. For example, a beetle is a Terrestrial Ecosystem Decomposer.

There are 3 diets of animals

Carnivores: An animal that only eats meat, or other animals.

Herbivore: A herbivore is an animal that only eats plants.

Omnivore: An omnivore is an animal that eats plants and animals
