What is the most abundant organism in a food chain​
Sholpan [36]

The given question is incomplete as there is no food chain given in the question, but based on the knowledge it can be said so that producers are present in abundant amount in every food chain.

Answer: Producers

Explanation:

The producers can be defined as the organism which have the ability to make food. This food is used by the other organism of the food chain as a soul source of energy.

They are huge in number so that they can produce enough food to meet the requirement of other organisms. Though all of the organisms are not directly dependent on producers ,some of them(carnivores) are also dependent on the organism eating plants(herbivores).

Producers→ primary consumers(herbivores)→ secondary consumers(carnivores)→tertiary consumers(carnivores).

Here, we can see that the all the organism are directly or indirectly dependent on the producers and they are abundant in every food chain.

marshall27 [118]

Answer:

Laws of stratigraphy help scientists determine the relative ages of rocks. This law states that deeper rock layers are older than layers closer to the surface. An unconformity is a gap in rock layers. They occur where older rock layers eroded completely before new rock layers were deposited.

Explanation:

The study of rock strata is called stratigraphy. The laws of stratigraphy can help scientists understand Earth’s past. The laws of stratigraphy are usually credited to a geologist from Denmark named Nicolas Steno. He lived in the 1600s.
