Which food chain is found in a water ecosystem?

Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Primary consumers are in turn eaten by fish, small sharks, corals, and baleen whales.

Which of the following is a food chain in a lake ecosystem?

Plants form the base of Great Lakes food chains. They’re called producers, because they make their own food by converting sunlight through photosynthesis. They also act as food, providing energy for other organisms. In the Great Lakes, most producers are phytoplankton, or microscopic floating plants.

What is food chain in ecosystem?

A food chain describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. … This site also tells us that because of our eating habits, we are in two food chains- marine and land.

What is a food chain in a river?

A food chain is a simple linkage of producers to consumers through feeding relationships. For example, when a small fish eats an aquatic insect, and a larger fish eats the small fish, the two fish and the insect are linked in a food chain. … A simplified view of a food web in a wooded stream is presented on the right.

Are zooplankton producers or consumers?

Zooplankton are the animal-like primary consumers of plankton communities. In turn, zooplankton then become food for larger, secondary consumers such as fish. Zooplankton include microscopic and macroscopic organisms.

What are the types of food chains?

There are two types of food chains, namely detritus food chain and grazing food chain.

What is an example of a pond food chain?

Check out this example of a small pond food chain: Hawk, snake, frog, insect, plant, sun. … Insects, like grasshoppers, eat the grass for their energy. Frogs, like a bullfrog, have to eat the grasshopper to get energy.

What are the 4 food chains?

The 4 levels of the food chain consist of: PRODUCERS: At the bottom of the food chain, plants are natural producers and provide food and nutrients to consumers. HERBIVORES: Herbivores nourish on plants and insects.

Table of Contents show

  • Primary producers.
  • Herbivores (consumers)
  • Carnivores.
  • Decomposers.

What are the 5 food chains?

Here are the five trophic levels:

  • Level 1: Plants (producers)
  • Level 2: Animals that eat plants or herbivores (primary consumers)
  • Level 3: Animals that eat herbivores (secondary consumers, carnivores)
  • Level 4: Animals that eat carnivores (tertiary consumers, carnivores)

What is a food chain answer?

food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant.

What is the ecosystem of a river?

River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.

What is the example of a food web?

eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected. eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal. The snake may eat a beetle, a caterpillar, or some other animal.

What is marine food chain?

Most marine species are tied together through the food web. … A food chain is a top-to-bottom set of animals and plants. They are linked to each other because those on top eat those below. Level One: Photoautotrophs. The bottom level of the ocean’s food chain is largely invisible.

What is zooplankton in the food chain?

Zooplankton are small, aquatic microorganisms in the water column that include crustaceans, rotifers, open water insect larvae and aquatic mites. The zooplankton community is composed of both primary consumers, which eat free-floating algae, and secondary consumers, which feed on other zooplankton.

What is a food chain producer?

Food Chains

Plants make their own food through a process called photosynthesis. Using the energy from the sun, water and carbon dioxide from the atmosphere and nutrients, they chemically make their own food. Since they make or produce their own food they are called producers.
