What else can I help you with?
When organisms become larger as they move up the food pyramid why does the biomass become smaller and why does the energy decrease?
As organisms move up the food pyramid, energy is lost through processes like respiration, movement, and waste production. This results in less energy being available for growth and reproduction, leading to a decrease in biomass as the organisms become larger. Additionally, only a fraction of the energy obtained from consuming food is converted into new biomass, with the rest being lost as heat energy.
Energy that is not available to other organisms in a food web is energy that is?
lost as heat and used for the organism's own metabolic processes. It is not passed on to other organisms through consuming.
Which trophic level contains the most available food energy?
On an ecological pyramid or in a food chain, typically, the highest trophic levels have the least amount of energy from the sun available for the next highest level. In a typical food chain, this would be the tertiary consumer level.
Why do food chains rarely consist of more than a few types of organisms?
This happens because the quantity of energy available in the organisms as food to the next trophic level decreases as you move through the food chain. For example, there may be 1000 Calories of food available if you eat the grass in a section of meadow, but only about 100 Calories in the grasshoppers in that section of meadow. That may not be enough food to support the things that eat grasshoppers, and so on. This limits the length and diversity of food chains. The longest and most complex food chains are in the open ocean!
Why must a food chain be kept at not more than 4 or 5 organisms?
Limiting a food chain to 4-5 organisms helps in maintaining energy efficiency as each organism at a trophic level only receives about 10% of the energy from the organism it consumes. With each transfer of energy, there is a loss of energy, so longer food chains would result in less energy being available to higher trophic levels. Additionally, having fewer organisms in a food chain reduces the risk of instability and collapse due to disruptions at any level.

How does the enegry in food become available to organisms?
vitamins,minerals,carbohydrates,calcium,iron .........etc
How is energy transferred among organisms?
Energy is transferred among organisms through food chains or food webs. Producers, such as plants, convert sunlight into energy through photosynthesis. This energy is then passed on to consumers through consumption of other organisms. Energy is lost as heat at each trophic level, resulting in less energy available for organisms at higher trophic levels.
Energy is available to organisms in the ecosystem because?
Energy is available to organisms in the ecosystem through the process of photosynthesis, where plants convert sunlight into chemical energy in the form of glucose. This energy is then passed through the food chain as organisms feed on one another, enabling all living organisms to grow, reproduce, and carry out their life processes.
Which process makes sunlight energy available to all organisms in an ecosystem?
Photosynthesis is the process by which sunlight energy is converted into chemical energy by plants. This energy is then transferred to other organisms in the ecosystem through food chains and webs.
Why is all the energy in one level of a food pyramid not available to the organisms at higher level?
its because that all the organisms get fit in one place.
The steps by which energy flows among a group of organisms is called?
A food chain.The steps by which energy flows among groups of organisms is called an energy pyramid. The energy pyramid shows what organisms get energy from other organisms and how much they get.
Energy that is not available to other organisms in a food web is energy that is?
lost as heat and used for the organism's own metabolic processes. It is not passed on to other organisms through consuming.
Explain how energy is transferred through a food chain?
Energy is transferred through a food chain as organisms consume other organisms. Primary producers, like plants, absorb energy from the sun through photosynthesis. Herbivores then consume plants, transferring the energy. Carnivores further transfer the energy by consuming herbivores. This process continues up the food chain, with each level of organisms consuming the energy stored in the organisms they consume.
Which trophic level contains the most available food energy?
On an ecological pyramid or in a food chain, typically, the highest trophic levels have the least amount of energy from the sun available for the next highest level. In a typical food chain, this would be the tertiary consumer level.
What do organisms get from food?
energy!
Why is food important to organisms?
Food provides organisms with necessary nutrients and energy.
