NEET BIOLOGY

Detailed explanation-1: -Energy flows through an ecosystem, while matter cycles within it.

Detailed explanation-2: -Transfer of Energy and Matter Pathways When one organism eats another, the matter, or carbon, nitrogen, and other essential elements, are transferred from one to the other. These elements move from the producers, to the consumers, and eventually to the decomposers, cycling the matter through the ecosystem.

Detailed explanation-3: -Unlike energy, matter is recycled in ecosystems. Decomposers release nutrients when they break down dead organisms. nutrients are taken up by plants through their roots. nutrients pass to primary consumers when they eat the plants.

Detailed explanation-4: -Elemental Cycles Energy flows but matter cycles, meaning that matter is not lost the way that energy can leave the system as heat. Instead, matter is retained in some form in the ecosystem.

Detailed explanation-5: -Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.
