yes
A food web is a diagram that shows how different food chains in an ecosystem are interconnected. It includes multiple food chains that overlap and demonstrate the various ways in which organisms in a community depend on each other for energy.
Not really, no. They depend on each other for safety's sake from predators, but not for food.
The living organisms depend on each other for their food & shelter. EG: Fungi and algae depend on each other .
Aquatic food chains are simpley water animals that eat plant,each other,or both.
Organisms depend on each other for food and shelter. For example, herbivores depend on plants for food, while plants depend on herbivores for pollination. Organisms also depend on each other for protection, such as cleaner fish removing parasites from larger fish in a mutualistic relationship.
You've already answered your own question. Dolphins depend on each other for protection, to help raise their young, and to find/kill food
Birds are part of both food chains. Many food chains in an environment can overlap with each other. A food web shows how a group of food chains are linked together.
A food web can contain multiple food chains, each representing a relationship between different organisms in an ecosystem where energy is passed along through feeding. The number of food chains in a food web depends on the complexity of the ecosystem and the number of organisms interacting with each other.
they depend on each other for food and nutrients. They even need each other for energy!
What kind of food chains there are in the mountains will depend on the mountain region. For example, the mountains near the Mohave will have a desert food chain.
so they can survive
Food chains and food webs are basically an organization, or hierarchy, that shows how living things depend on each other to live. They describe the 'order' of an ecosystem and show which organisms/living things become food for an another organism/living thing that's 'higher up' on the food chain. Food chains are very important. For example, if a certain species of animal died out, then the animal that eats them will be affected (because their food supply has just died out). They allow you to view the way in which ecosystems work and how other species would be affected by changes in either the environment or survival of other species.
