Answer:
The plants in an ecosystem produce food for most of the other organisras that live in that ecosystem. The role of a plant in its ecosystem is its <em>trophic level</em>
Explanation:
Plants are the least to be found in the trophic level, they are otherwisely called <em>autotrophs. </em>They make food for themselves while others among the trophic level depend on them
Answer:
Process of Green Revolution
Explanation:
Answer:
Mitocondria is responsible for the reactions in cellular respiration.
Explanation:
Mitochondria have an important role in cellular respiration through the production of ATP, using chemical energy found in glucose and other nutrients. Mitochondria are also responsible for generating clusters of iron and sulfur, which are important cofactors of many enzymes.
Answer:
<u>The bacterial cell because it has the largest surface-to-volume-ratio.</u>
Explanation:
The rate of diffusion in and out of a body depends on surface area to volume ratio. The higher the ratio the greater the rate of diffusion and the lower the ratio, the lower the rate of diffusion.
This implies that small organisms like the bacteria cell expose a large surface area to the surrounding when compared to big organism cells. Therefore, small organisms depend on diffusion as a means of transport of foods, respiratory gases and waste products.
Large organisms, in addition to diffusion have trasnport systems to increase the efficiency of diffusion.
