Will give 20 points and mark brainliest what is most likely the amount of energy available at a trophic level of primary consumers if the amount of energy available to producers in that food web is 2,000 kilocalories?
200 kilocalories

2,500 kilocalories
3,000 kilocalories

200 kilocalories

Explanation:

According to the 10 per cent law of energy, only 10 percent energy is transferred from one tropic level to another tropic level.

The producers has the maximum amount of energy because they trap sunlight and make food by the help of process known as photosynthesis.

The energy from the producers is transferred to primary consumers. This energy is 10 per cent the total energy producers has.

If the producers have 2000 kilocalories then 10% of 2000 = 200. Hence the primary consumers will have 200 kilocalories.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
