The primary souce is the SUN
food webs contain many food chains however a food chain shows only one primary source and food webs contain more than one primary source.
It is the sun.
The sun
Primary succession creates new habitats, allowing for the establishment of diverse plant and animal species in an ecosystem. This increases the variety of organisms available as food sources, which in turn can enhance the complexity and stability of food chains and food webs within the ecosystem.
Producers are the food for primary consumers.
The energy from the sun!
A food web is many food chains.
yes
Food webs on land typically have a more complex structure with more levels of consumers compared to those in water. On land, primary producers are mostly plants, while in water, phytoplankton are a major source of primary production. Additionally, terrestrial food webs have more diverse animal species due to the higher availability of resources on land.
Amoebas are typically found at the bottom of the food chain as primary consumers. They feed on microscopic organisms like bacteria and algae, playing a vital role in breaking down organic matter and recycling nutrients in ecosystems. Larger organisms then consume amoebas as a food source, continuing the transfer of energy up the food chain.
the source for all enery is sunlight
In most food webs the Sun is the ultimate source of energy. Some food webs start with chemotrophs and in those cases the source of the energy are chemicals often from underwater volcanoes.
