Question

question 1
how are the atmosphere, hydrosphere, and lithosphere related in the biosphere?

question 2
compare and contrast food webs and food chains.

question 3
in the following food chain, which part contains the most biomass?
green plants → rabbits → owls

Explanation:

Question 1: The biosphere is the global sum of all ecosystems. The atmosphere provides gases like oxygen and carbon - dioxide for life in the biosphere. The hydrosphere supplies water, essential for all living organisms. The lithosphere provides the solid surface for plants to grow and animals to live on. They interact in processes like the water cycle, carbon cycle, etc.
Question 2: Food chains represent a linear sequence of organisms where each is eaten by the next one in the chain. Food webs are more complex and are a network of interconnected food chains. Food chains are simple models, while food webs show the multiple feeding relationships in an ecosystem.
Question 3: In a food chain, the producers (green plants) contain the most biomass. They convert solar energy into chemical energy through photosynthesis and form the base of the food chain, supporting higher - trophic levels.

Answer:

Question 1: The atmosphere provides gases, the hydrosphere provides water, and the lithosphere provides a surface for life in the biosphere, and they interact in biogeochemical cycles.
Question 2: Food chains are linear sequences of organisms with one - way energy flow, while food webs are networks of interconnected food chains showing multiple feeding relationships.
Question 3: Green plants
