Difference between food web and food chain :-
Food web:- It consists of many food chains connected together . A food web shows many different paths plants and animals are connected.
Food chain:- It is the pattern that energy uses to transmit to producers to decomposers. It only follows just one path as animals find food. Eg:- A hawk eats a snake, which has eaten a frog, which has eaten grass.

What is a food chain? What is a food web? What are trophic levels? (see class notes and Campbell pp. 1221-1223) What is the role of primary producers in food chains? Why is the biomass of consumers in a community determined by the net primary production (NPP) of the autotrophs in a community. What abiotic environmental factors affect the net primary production in a community? Gives examples of some communities with high NPP and some with low NPP. Open Ocean...
NPP = GPP – R Net primary production = ______________ = GPP – energy used for cellular respiration Gross primary production = ________________ production of primary producers Respiration = ______________________ Thus NPP is the amount of energy available to primary consumers = primary production Explain the different ways in which primary production is influenced in terrestrial and aquatic ecosystems Primary production: terrestrial ecosystems influenced by water, temperature, and nutrient availability Evapotranspiration rate measures the amount of water entering the atmosphere...
10. Describe the different stages of a food chain. What is the difference between a food chain and a food web? What is trophic efficiency? What is the distribution of biomass between different trophic levels in the ocean?
Define and provide examples of the following concepts: Environment, ecosystem, abiotic and biotic factors, natural and experimental boundaries, flows of matter and energy. Explain how the boundaries of an ecosystem may differ from those like national parks, county, state or national borders. Explain how natural features of the landscape (ex: a watershed) or biological phenomena (ex: a species range) can be used to define the boundaries of an ecosystem. Explain how ecosystems vary in size and scale, and how some...
