Question

review key concepts

1. a. review how does the way that matter flows through an ecosystem differ from the way that energy flows?

b. apply concepts what are the four types of processes that cycle matter through the biosphere? give an example of each.

1. a. review by what two processes is water cycled from land to the atmosphere?

b. sequence describe one way in which water from the ocean may make one complete cycle through the atmosphere and back to the ocean. include the names of each process involved in your cycle.

1. a. review why do living organisms need nutrients?

b. predict based on your knowledge of the carbon - cycle, what do you think might happen if humans were to continue to clear and burn vast areas of forests for building?

1. a. review explain how a nutrient can be a limiting factor in an ecosystem.

b. apply concepts look back at the nitrogen and phosphorus cycles (figures 3 - 18 and 3 - 19). how is fertilizer runoff related to algal blooms?
write about science

1. describe how oxygen, although it does not have an independent cycle, moves through the biosphere as part of the carbon cycle. include a description of the various forms that oxygen takes.

Explanation:

1.

Step1: Matter flow in ecosystem

Matter is recycled in an ecosystem through biogeochemical cycles like carbon - cycle, nitrogen - cycle etc. It moves between living organisms and the environment. Energy, on the other hand, flows in one direction from the sun to producers, then to consumers and finally dissipates as heat.

Step2: Four processes of carbon - cycle in biosphere

The four processes are photosynthesis (plants take in carbon - dioxide and convert it to organic carbon), respiration (organisms release carbon - dioxide back to the atmosphere), decomposition (organic matter is broken down and carbon is released), and combustion (burning of fossil fuels and biomass releases carbon - dioxide).

Step1: Water cycle processes

Water is cycled from land to the atmosphere through evaporation (water changes from liquid to gas from surfaces like lakes, rivers) and transpiration (plants release water vapor).

Step2: Ocean - atmosphere water cycle

Water evaporates from the ocean surface, forms clouds through condensation. Then it falls back to the ocean as precipitation.

Step1: Importance of nutrients for organisms

Living organisms need nutrients like carbon, nitrogen, phosphorus etc. for growth, repair of tissues, energy production, and for carrying out biochemical reactions. For example, nitrogen is needed for protein synthesis and DNA formation.

Answer:

a. Matter is recycled in ecosystem while energy flows in one - direction. b. Photosynthesis, respiration, decomposition, combustion.
