Question: What is the original source of the energy that flows through most ecosystems what would happen without this source?

Solar energy is the original source of energy in most ecosystems. There must be a continual supply, due to energy only flowing in one direction in an ecosystem. Energy that is lost to heat must be replaced by more energy.

What is the original source of the energy that flows through most ecosystem?

In most ecosystems, the ultimate source of all energy is the sun.

What is the original source of energy for most ecosystems A grass b humans C The Sun d heat?

The source of all energy in most ecosystems is the sun.

Why are there fewer consumers at the top of the energy pyramid?

The organisms that eat the producers are the primary consumers. … Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.

Why would there be fewer organisms at level A than at any level below it?

With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass.

What is the flow of energy in a food chain?

The flow of energy in an ecosystem is always linear ie uni direction. At each energy step in food chain, the energy received by the organisms is used for its own metabolism and maintenance. The left over energy is passed to next higher trophic level. Thus the energy flow decreases with successive trophic level.

Which of the following is one way that energy flows in an ecosystem?

Energy flows through an ecosystem in a one-way stream, from primary producers to various consumers.

What is ecosystem explain energy flow in ecosystem?

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.

How does energy move through most ecosystems on Earth?

The Flow of Energy

Most ecosystems get their energy from the Sun. … Producers convert the sunlight into chemical energy or food. Consumers get some of that energy when they eat producers. They also pass some of the energy on to other consumers when they are eaten.

What is the ultimate source of energy for most organisms and how is this energy captured so it is useful in a food chain?

The sun is the ultimate source of energy for all food chains. Through the process of photosynthesis, plants use light energy from the sun to make food energy. Energy flows, or is transferred through the system as one organism consumes another.

Why there are fewer organisms at the top of the energy pyramid compared to the bottom?

The number of organisms at each level decreases relative to the level below because there is less energy available to support those organisms. The top level of an energy pyramid has the fewest organisms because it has the least amount of energy.

Why is there less energy and usually fewer organisms in the top of the energy pyramid than there is in the bottom of the energy pyramid?

The top level of an energy pyramid has the fewest organisms because it has the least amount of energy. Eventually there is not enough energy left to support another trophic level; thus most ecosystems only have four trophic levels.

Why there are fewer animals at the top of the pyramid than at the bottom?

As you go up the trophic pyramid, the total number of organisms (or biomass) at the next level decreases because much of the original energy captured from the sun during photosynthesis is lost at each level of the trophic pyramid (see explanation below). Consumers at the highest trophic level are called apex predators.

Why do populations of organisms decrease as the level gets higher?

Why do populations decrease at higher trophic levels? … The population size decreases because the higher on the food chain one looks, the fewer the number of organisms that occupy that level. This is because of the energy that is available from one level to the next has to decrease since it is used for life’s process.
