Explain how enery and nutrients enter move trough and exit a food chain in an ecosystem?
Energy enters a food chain through primary producers (plants) that convert sunlight into chemical energy through photosynthesis. This energy is passed on to herbivores that eat the plants, and then to carnivores that eat the herbivores. Nutrients are cycled through the food chain as organisms consume each other or decompose after death, releasing nutrients back into the ecosystem. Exiting the food chain, energy is lost as heat at each trophic level, eventually exiting the ecosystem, primarily through decomposition and respiration.
How does energy from the sun enter livings systems such as plants?
Energy from the sun enters living systems through a process called photosynthesis. In plants, chlorophyll absorbs sunlight, which is used to convert carbon dioxide and water into glucose (sugar) and oxygen. This process is essential for the survival of plants and the food chain.
How does the energy enter the biosphere?
Energy enters the biosphere primarily through sunlight, which is captured by plants during photosynthesis. This energy is then transferred through the food chain as organisms consume each other. Additionally, some energy enters the biosphere through geothermal sources.
How much total energy is lost from a three step food chain if 1000 calories enter at the autotroph level?
In a three-step food chain, about 90% of energy is lost at each trophic level through metabolism and heat production. Therefore, if 1000 calories enter at the autotroph level, approximately 100 calories would reach the tertiary consumer level.
Where do electrons that flow through the two photosystems have their highest potential energy?
The electrons that flow through the two photosystems in the light-dependent reactions of photosynthesis have their highest potential energy at the beginning, when they are excited by sunlight and enter the electron transport chain. This potential energy is used to create a proton gradient across the thylakoid membrane, which is then harnessed to produce ATP through ATP synthase.
How does energy enter this food chain?
Energy enters a food chain through primary producers like plants, which capture sunlight and convert it into chemical energy through photosynthesis. This energy is then passed on to primary consumers (herbivores) who eat the plants, and then to secondary consumers (carnivores) who eat the herbivores, and so on. Each time energy is transferred, some is lost as heat through metabolic processes.
How does energy first enter a pond ecosystem?
Energy first enters a pond ecosystem through sunlight. Sunlight is captured by plants through photosynthesis, which converts light energy into chemical energy. This energy is then transferred through the food chain as other organisms consume the plants or other organisms that have consumed the plants.
How does the suns energy enter the biological world?
The sun's energy enters the biological world through photosynthesis. Plants capture sunlight and convert it into chemical energy in the form of glucose through this process. This energy is then transferred through the food chain as organisms consume plants or other organisms.
How Does Energy Enter And Leave Grazing Food Chain?
In a grazing food chain, energy enters primarily through photosynthesis, as plants (producers) convert sunlight into chemical energy. Herbivores (primary consumers) then consume these plants, transferring energy up the chain. As energy moves to higher trophic levels, such as carnivores (secondary consumers), a significant amount is lost as heat through metabolic processes. Ultimately, energy leaves the food chain when organisms die and decompose, returning nutrients to the soil, or through respiration and waste products.
How does sunlight energy enter the biotic world?
Sunlight energy enters the biotic world through the process of photosynthesis, where plants and other photosynthetic organisms convert sunlight into chemical energy in the form of glucose. This energy is then transferred through the food chain as animals consume these plants for energy.

How does nitrogen enter the food chain?
Nitrogen enters the food chain through nitrogen-fixing bacteria which convert atmospheric nitrogen into a form that plants can absorb. Plants then take up this nitrogen through their roots and incorporate it into their tissues. When herbivores eat these plants, they obtain the nitrogen, and it continues up the food chain when carnivores eat the herbivores.
What are the 2 energy carriers that enter the electron transport chain and their energy can be transferred to ATP?
FAD and NADHThe pick up electrons, with attendant protons, to carry into the transport chain and become,FADH and NADH2
How does the DDT originnaly enter the food chain?
DDT originally enters the food chain through runoff from agricultural fields or from direct application to crops. It can then be absorbed by plants and accumulate in the tissues of animals that eat these plants. This process is known as bioaccumulation.
How does energy get from the sun to a second level consumer?
energy from the sun is taken by plants in the process of photosynthesis to form glucose from CO2 and H2O. The plants have a compound in their green leaves cells called chlorophyll which is enables the cell to trap sun rays or light particles called photon and so through plants and algae sun energy enter into food chain
