b) The oxygen concentration of the water
c) Rocks on the ocean floor
d) The temperature of the water

Answer 1

Answer:

A

Explanation:

In a marine ecosystem, some of the biotic factor are algae, fungi, microorganisms (such as bacteria), plants, animals and corals. These living beings compete against each other for food and resources, are part of the predator-prey relation, and also include the decomposers.

Biotic components are living organisms in an ecosystem. A biotic factor is a living organism that affects another organism in its ecosystem. Examples include plants and animals that the organism consumes as food, and animals that consume the organism

Answer 2

In an ecosystem, the biotic and abiotic components are interdependent and interrelated to each other.

The biotic components of the marine ecosystem are phytoplankton on the surface of the ocean.

The abiotic and biotic factors of ecosystems are:

• Biotic components of the ecosystems are phytoplanktons, plants, and some algae. Phytoplanktons are microscopic organisms, which produce food for the other heterotrophs.

• The abiotic components are the non-living things that regulate the ecosystem and are directly or indirectly dependent on the biotic components.

Thus, the biotic components of marine ecosystems are phytoplanktons.
