What is at the bottom of a marine food chain?

Answer 1

At the bottom of any food chain are the producers. Generally producers are thought of as being "green plants". A producer need not be green, (diatoms, red algae brown algae, chemosynthetic bacteria as in the ocean deeps by hot-water vents are examples of non-green producers). The foregoing are not even vascular plants. Perhaps the producer organisms responsible for the greatest food production would be the phytoplankton of the oceans.

If an organism is being sought as the occupier of the bottom of a food chain or web, I agree. However, at the bottom of any food chain or web I would place an energy source. The food pyramid sits upon one or several energy sources. It is not an organism, but I believe it must precede any organism capable of synthesizing a food. Perhaps the question now may be, "What was the first energy incorporating organism?"

Answer 2

Animals that are at the bottom of the food chain include plants, shrubs, algae, and other forms of vegetation. sunlight is considered to be at the bottom of the food chain because plants consume it, but sunlight is not an animal.

Herbivores. They can also be called primary consumers, first consumers, first level consumers, etc. They are the organisms that eat the producers in the food chain. (I know this because it is what my science class is doing now.)

Answer 3

The food chain begins with plankton. There are 2 types of plankton. Zooplankton and phytoplankton. Phytoplankton are plants and zooplankton are animals.

Answer 4

the person who disrespects, usse, scavanges,and lives off others for their own personal gain.

Answer 5

I think it is the plankton but im not entirely sure.

Answer 6

The top predator (usually a tertiary or terciary consumer). Case by case scenario, since even the top predator can still be hunted.
