How do biotic factors contribute to the carbon cycle?

How do biotic factors contribute to the carbon cycle?

Thus, an abiotic factor (carbon dioxide) helps create a biotic factor (the plants made out of carbohydrates). Once cellular respiration starts in the organism, it releases Carbon dioxide back into the atmosphere, and the cycle repeats.

How does carbon dioxide get into the ocean?

The ocean takes up carbon dioxide through photosynthesis by plant-like organisms (phytoplankton), as well as by simple chemistry: carbon dioxide dissolves in water. The new water takes up yet more carbon to match the atmosphere, while the old water carries the carbon it has captured into the ocean.

What are some biotic factors in the marine biome?

Biotic factors include plants, animals, and microbes; important abiotic factors include the amount of sunlight in the ecosystem, the amount of oxygen and nutrients dissolved in the water, proximity to land, depth, and temperature. Sunlight is one the most important abiotic factors for marine ecosystems.

How do marine animals use carbon What carbon compound do they use?

Carbon dioxide from the atmosphere dissolves in the surface waters of the ocean. Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter. Many organisms use carbon to make calcium carbonate, a building material of shells and skeletons.

What organisms release carbon dioxide as waste?

Animals release waste carbon dioxide when they exhale or breathe out. When decomposers break down dead plants and animals, they too release carbon dioxide. All of the carbon dioxide released into the air by these processes is available to plants for photosynthesis.

Do producers release carbon dioxide as waste?

The producers take up oxygen from the environment which can be utilized to break down the food in the form of glucose into simple substances along with the release of energy and carbon dioxide as a metabolic waste.

How is carbon dioxide recycled back into the food chain?

Processes in the carbon cycle Carbon dioxide is absorbed by producers to make glucose in photosynthesis. Animals feed on the plant passing the carbon compounds along the food chain. Decomposers break down the dead organisms and return the carbon in their bodies to the atmosphere as carbon dioxide by respiration.

What is the primary source of energy in a food chain oxygen Sun carbon dioxide water?

Photosynthesis. Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Which organism has the least energy in a food chain?

It follows that the carnivores (secondary consumers) that feed on herbivores and detritivores and those that eat other carnivores (tertiary consumers) have the lowest amount of energy available to them.

What is at the top of the food chain in the ocean?

The orca, or killer whale is at the top of the marine food chain. In spite of the fact that they are called “killer whales,” orcas are actually dolphins. Orcas have 4-inch long teeth that they use to feast on other ocean animals, which can include seals, sea lions, sharks, seabirds, fish, and even whales.

What is the difference between a first-level consumer and a second level consumer?

Why? They are first-level consumers because they eat producers, (plants, bacteria, algae,), and are either herbivores or omnivores. They have predators, obviously, and their main predators are second-level consumers, even though decomposers/scavengers eat their remains and third-level consumers may eat them.

What organisms are first level consumers?

First-level consumers, also known as primary consumers, eat producers such as plants, algae and bacteria. Producers comprise the first trophic level. Herbivores, the first-level consumers, occupy the second trophic level. First-level consumers do not eat other consumers, only plants or other producers.

What is an example of a second level consumer?

Second Level Secondary consumers get their energy from primary consumers and herbivores in their ecosystems. For example, a toad living in the woods eats grasshoppers and other insects. Secondary consumers may be strictly meat eaters — carnivores — or they may be omnivores, eating both plants and animals.
