Describe the energy flow in an ecosystem.
Answers
Explanation:
1)An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact.
2) The main components are biotic and abiotic components . The main source of energy is sun.
3)These biotic and abiotic components are linked together through nutrient cycles and energy flows

Answer:
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. ... Ecosystems can be very large or very small.
The two component of ecosystem are biotic (living) and abiotic (nonliving) components.
In most ecosystems, the ultimate source of all energy is the sun.
Green plants absorb most of the energy that is incident on them and by the process of photosynthesis they produce food for the consumers. Thus, they serve as the primary producers in the ecosystem. They also help in maintaining the balance of Oxygen and Carbon dioxide on earth.
Producers are the living organisms which help to produce food from sunlight, soil and air. Consumers are the living organisms which depend directly and indirectly on other organisms for their food.
Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers
A food chain is a linear network of links in a food web starting from producer organisms and ending at an apex predator species, detritivores, or decomposer species. A food chain also shows how organisms are related to each other by the food they eat. Each level of a food chain represents a different trophic level.
Energy flow is the flow of energy through living things within an ecosystem. All living organisms can be organized into producers and consumers, and those producers and consumers can further be organized into a food chain. Each of the levels within the food chain is a trophic level.
