The first trophic level of the food chain has the most energy. This level contains the producers , which are all of the photosynthetic organisms.
Which organism has the most available energy in an ocean food web?
Autotrophs are also known as primary producers, and are are a highly important food source for other organisms. On land, primary producers are mostly plants such as grass in trees. In the ocean, 95% of the primary production is done by microscopic phytoplankton .
Which organism has the most available energy sea urchin?
The first trophic level of the food chain has the most energy. This level contains the producers , which are all of the photosynthetic organisms.
Which statements describe the energy in a food web?
Answer: Producers have the greatest amount of available energy , Energy can follow many different paths. When an organism eats another organism, it gains energy.
What are the 4 levels of the energy pyramid?
- Producers. The producers and the energy available within them occupy the first level of the energy pyramid. ...
- Primary Consumers. The second level of the energy pyramid is represented by primary consumers, which are usually herbivores. ...
- Secondary Consumers. ...
- Tertiary Consumers.
Which organism gets the least amount of energy?
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 are 3 consumers in the ocean?
Primary consumers in the ocean include zooplankton, small fish, and crustaceans . The secondary consumers are fish, coral, penguins, whales, and other species that eat the zooplankton. The top predators in the ocean, sharks, killer whales, and leopard seals, eat both primary and secondary consumers.
What eats a jellyfish?
Sea anemones may eat jellyfish that drift into their range. Other predators include tunas, sharks, swordfish, sea turtles and penguins. ... In general however, few animals prey on jellyfish; they can broadly be considered to be top predators in the food chain.
What are the 4 food chains?
On the blackboard, write the following headings: Producers, Primary Consumers, Secondary Consumers, and Tertiary Consumers . Ask students to name some species under each heading. Then demonstrate how to create a food chain, using some of the species listed.
Which organism is both a secondary and tertiary consumer?
Sample answers: Primary consumers: cows, rabbits, tadpoles, ants, zooplankton, mice. Secondary consumers: frogs, small fish, krill, spiders. Tertiary consumers: snakes, raccoons, foxes , fish.
What shows how much energy is in matter?
A pyramid of energy shows how much energy is retained in the form of new biomass at each trophic level, while a pyramid of biomass shows how much biomass (the amount of living or organic matter present in an organism) is present in the organisms.
What are the roles of consumers?
Organisms interact with each other and their environment in ecosystems. The role of consumers in an ecosystem is to obtain energy by feeding on other organisms and sometimes transfer energy to other consumers . Changes that affect consumers can impact other organisms within the ecosystem.
Which part of the pyramid has the most energy?
The bottom and largest level of the pyramid is the producers and contains the largest amount of energy. As you move up the pyramid, through the trophic levels to primary, secondary and tertiary consumers, the amount of energy decreases and the levels become smaller.
What is energy pyramid explain with diagram?
An energy pyramid is a model that shows the flow of energy from one trophic, or feeding, level to the next in an ecosystem . The model is a diagram that compares the energy used by organisms at each trophic level. The energy in an energy pyramid is measured in units of kilocalories (kcal).
Where are humans on the energy pyramid?
The World's Food Chain
Right above them are herbivores, such as rabbits, cows and deer, which have a trophic level of 2. Next come the omnivores that eat a mixture of plants and herbivores. That's where humans rank, with a trophic level of 2.2 .
Which organism number is less in food chain?
The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers . The secondary consumers tend to be larger and fewer in number. This continues on, all the way up to the top of the food chain.
