Which of the following would be located at the bottom of an energy pyramid found in the ocean?

shark

crustaceans

small fish

phytoplankton

Option D, Phytoplanktons

Explanation:

In an energy pyramid, producer i.e an organism which is able to make food lies at the bottom.

Phytoplanktons are able to entrap the carbon dioxide from the ocean and sunlight to produce food through the process of photosynthesis. This food is consumed by all aquatic organisms directly or indirectly.

Thus, pytoplanktons can be considered as the producer of the aquatic ecosystem.

Being the producer, phytoplanktons lie at the bottom of the energy pyramid found in the ocean.

We are just like other organisms. The main purpose of animals is to survive and expand the population. Humans are meant to do the same thing however our brains evolved in a more sophisticated way. Humans originated from Africa. The place where our ancestors come from became very hot, dry and drought-like after a period of nice hot climates. This change in climates forced our brain to think a critically think and resulted in a "mutation". This mutation resulted in a complete change in the way think and ended up making us the smartest creatures in the world. We were more intelligent than the other creatures and know how to survive and adapt to different environments. Also, just like animals, we are meant to maintain our place in the food chain and environment. As animals we are supposed to not affect environments negatively and make sure that we survive while giving other animals their place in the ecosystem.
