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?"
What else can I help you with?
These are often at the bottom of most food chains?
there are often at the bottom of food chains. Plants
The bottom of the food chains?
plants
These are often at the bottom of the food chain?
Producers and then herbivors are often at the bottom of the food chains.
What animal that are often at the bottom of a food chain?
Bottom? The producer, e.g. a plant, trees Top? The carnivore, eats plants and animals, e.g. eagle Animals at the bottom if food chains are ones that eat plants. These are called herbivores. They are usually catapillars and other insects.
What is a model that shows how food chains are connected?
They are called food chains.
What food chains can you find in central valley California?
food chains
What does an overlapping food chains in an ecosystem make up?
Food Chains! :)
What do food webs show us what food chains dont?
Food webs and food chains are mostly the same
What can a food web be broken down into?
From what I learned in my science class we would always Put the decomposers at the very bottom but I don't know if that is correct.since a food web is many overlapping food chains that show how energy flows through an ecosystem I think that the producers should be at the very bottom. Sorry
What is the term used to describe food chains which overlap and intersect?
The term used to describe food chains that overlap and intersect is called a food web. A food web consists of multiple food chains in an ecosystem.
In food chains why do the arrows flow from the bottom upwards?
The energy is transferred from a lower trophic level to a higher trophic level when resources are consumed.
A diagram that shows overlapping food chains?
overlapping food chains are called a food web.
