Answer:
Plants may compete with other organisms like phytoplankton for sunlight, their source of light energy for photosynthetic reactions.
Explanation:
Abiotic factors or non-living factors in terrestrial ecosystems include temperature, rainfail, and light; in other aquatic ecosystems, they also include salinity, and water currents.
Plant populations belong to the biotic factors within an environment, and often complete with other organisms such as fungi, animals and bacteria.
For instance, plants share their photosynthetic ability with some bacteria. In aquatic biomes, both phytoplankton, and aquatic plants compete for available sunlight underwater in order to make energy via photosynthesis.
Answer:
300 kcal of energy.
Explanation:
Grass produces 30,000 kcal of energy through the process of photosynthesis. The zebra eat this grass and would acquire 3000 kcal of energy because only 10% of energy will transferred from one trophic level to another. In this way, when the cheetah feed on zebra, it acquire 300 kcal of energy and again 10% of energy is transferred from zebra to cheetah while the remaining release in the atmosphere in the form of heat energy.
Proteins are broken down into amino acids, while carbohydrates are broken down into sugars.
I’d say the best answer is a and c
