What else can I help you with?
As we move along the food chain does the energy increase or decreases and why?
Energy decreases as we go up the food chain because there are less organisms as we go up, so that the ecosystem doesn't run out of food at the bottom of the chain.
Does energy and biomass increase or decrease as you go through the food chain?
Energy and biomass decrease as you move up the food chain due to the second law of thermodynamics, which states that energy is lost as it moves through trophic levels. Organisms higher up in the food chain have less energy available to them compared to those lower down.
Why is there less energy at the end of a food chain?
Energy is lost at each step of a food chain through processes like respiration, heat loss, and waste production. As a result, only a fraction of the energy from one trophic level is passed on to the next, leading to a decrease in available energy as you move up the food chain.
What travels through the food chain?
Energy. In general, only about 10% of the energy available is able to be passed up the food chain.
Is it true electrons gain energy as they move down the chain?
No. Electrons gain energy as they move up the chain, i.e. in more outer shells.
What is the Energy that drives the food chain?
Ultimately, the energy that drives a food chain is solar energy. Plants absorb and convert this energy, which insects, birds, and other herbivores transfer up the food chain until it reaches humans.
Why only a small amount of the energy stored in food is available for the next organism in a food chain?
The energy stored in food is lost as heat during metabolism, movement, and other activities by the organism. This limits the amount of energy that can be passed on to the next organism in the food chain. As a result, only about 10% of the energy is transferred to the next trophic level, leading to a decrease in available energy as you move up the food chain.
How energy flows through a food chain and a food web?
Energy flows up a food chain, from the primary producers to the primary consumers, to the secondary consumers, up to the tertiary and then quaternary consumers. Energy flows when one organism eats another.
What happens to energy as you move from step in a chain or web?
The energy decreases as you move step to step in a chain The first organism (primary consumer) that eats the producer (green plants) will have the most number
Why are the producers always the start of the food chain?
If you have a food chain then the chain must have a beginning (where the food is made) and an end (where the food is finally all used up). Thius in a food chain the "producers" of the food (the plants) are ALWAYS the start. The plants make food using CO2 from the air, Water from the ground and the energy they collect from Sunlight. It is the passing on of this energy from the Sun that is the chain.
What limits the number of links in a food chain?
The number of links in a food chain is limited by the amount of available energy. As energy is transferred up the food chain, only about 10% is passed on to the next level. This inefficiency limits the number of trophic levels that can be sustained in a food chain.
Why would it be rare to find a food chain with nine links in it?
because energy has to travel up the food chain, and by the 9th link there is very little energy for the animal to use
