In an ecosystem with four levels producers, primary consumers, and two higher-level consumers describe where the decomposers operate within the context of these trophic levels. Can you give me two examples?

You are studying primary productivity and biodiversity patterns of an ecosystem. The ecosystem is represented by the climatograph below. The Gross Primary Productivity (GPP) is measured to be 5000 grams of carbon per square meter per year, and the Total Respiration (RT) is measured to be 300 grams of carbon per square meter per year.  - What kind of biome is this? - Calculate the Net Ecosystem Production (NEP) for this ecosystem - What does the calculated NEP value indicate about the carbon balance and overall productivity of the ecosystem? (one sentence) - Based on both the climatograph and the NEP, what can you say about the biodiversity of plants versus consumers? Choice 1 of 4:plant biodiversity is greater than consumer biodiversity Choice 2 of 4:consumer biodiversity is greater than plant biodiversity Choice 3 of 4:consumer biodiversity is the same as plant biodiversity Choice 4 of 4:lower plant biodiversity compared to consumer biodiversity

Explain the solution for the removal of water flies. How will this solution affect the native species, economy, and/or social impacts? How long do you think it will take to return to the original biodiversity of the ecosystem based on this solution and why?

The trophic levels found in this ecosystem are decomposers, producers, consumers, secondary consumers, and top predators. Which one of these converts light energy into chemical energy?

We discussed several trophic pyramid shapes in relation to energy, biomass, aquatic, and terrestrial communities. In which system do we display the pyramid as inverted/upside down? Group of answer choices Terrestrial energy Aquatic biomass Terrestrial biomass Aquatic energy

The term gross primary productivity refers to the:    Question 12 options:   Rate at which the primary producers can incorporate energy from the sun.   Total weight of the living or previously living organisms in an area at one time.   The way in which persistent toxic molecules build in concentration in higher trophic levels.   An organism that can make its own food using energy from inorganic molecules instead of the sun.

What does each pie slice represent?   a. Amount of energy available to support each trophic level b. Amount of energy that can be converted to biomass at a higher trophic level c. Amount of energy available from the sun d. Inefficiency of energy flow from one trophic level to the next

Which of these hypotheses does not explain why increased CO2 levels in the atmosphere could cause a decrease in the productivity of some crops because of changes in climate?   A) There could be increases in average winter temperatures that reduce the growth of crops. B) There could be decreases in precipitation in some regions that reduce growth in some crops. C) There could be shifts in the ranges of some important species in the community, such as pollinators, that cause reduction of growth in some crops.

The box-and-arrow model below summarizes some of the feedback links observed in the Amazon rain forest. Select true statements, based on whether they are represented by the model. (Note that the boxes and arrows in this model are used differently than those in the nutrient cycle models.) Select all of the ones that apply.  A) An increase in CO2 increases the frequency of droughts. B) The death of trees promotes the invasion of grasses. C) Tree growth reduces atmospheric CO2. D) The burning of fossil fuels increases atmospheric CO2. E) Drought increases the frequency of forest fires.
