Answer:
<em>The correct option is D. 10</em>
Explanation:
Energy gets transferred from one trophic level to another when an organism consumes the organism below it on the trophic level pyramid. However, most of the energy is lost at each trophic levels. Ecologists have made observations and illustrated that only 10% of energy gets transferred from one trophic level to another.
For example, let's consider the energy in producers to be 100%. the energy transferred by them to the primary consumers will be 10%. The energy transferred from the primary consumers to secondary consumers will be 1%.
Answer:
Humus (hummus) is a dark organic matter in the soil which is produced by the decay of leaves or twigs (leaf litter). The litter is decayed in the soil by the action of microbial communities and chemcial reactions (together called as biogeochemical reactions). This process is also known as decomposition. The higher humus content in the soil makes it more fertile because there are more nutrients releasing due to increased turnover of the decomposing bacteria. Further, humus formation is increased if more water (moisture content) and oxygen is available.
1)-c it means plants as producer
2)-c consumer take other organism as food so they are consumer
Since chloroplast use energy to make food for plant cells (Photosynthesis) I could compare it to lunch money, and how you have to keep refilling up, and up, just to use it again for food, for yourself.
Answer:
All prokaryotic cells have a nucleoid region, DNA and RNA as their genetic material, ribosomes that make proteins, and cytoplasm that contains a cytoskeleton, which organizes and supports the parts of the cell.
