What are the primary producers of our planet's food chain and where does the initial energy come from?

Answer 1

plants... energy comes from the sun

Answer 2

The sun provides the energy to move electrons and split water to begin photosynthesis in plants. This ends in the production of G3P which can be converted into glucose and starch (the storage materials of plants). Phytoplankton are also primary producers in the ocean. They are able to undergo a process similar to photosynthesis. They obtain their initial energy from the sun. They're also eaten by zooplanton which are eaten by fish and whales and whatnot.

Answer 3

The initial energy comes from the sun. The sunlight induces glucose (it's a sugar) synthesis in plants and photosynthetic algae, animals feed on plants, other animals feed on plant-eating animals. Then, plants and animals die and are eaten by bacteria. The cycle of life.
You should also note that in some places, such as dark depths of oceans and deep underground live organisms (mostly bacteriae) whose existence does not depend on sunlight. They take the initial energy from some source of heat.

Answer 4

the sun provides the energy to the plants so the sun provides the energy and the plants are the primary producers.

Answer 5

Algae is one of the primary producers and it gets energy from the sun.

Answer 6

I think that plants are what everything eats that provide all things with energy that they, themselves, got from the sun, via photosynthesis, unless I'm saddly mistaken. This cycle begins the "food chain", "thing" that helps to sustain humans.

Answer 7

Phytoplanktons
