Net ecosystem production is de fined as net primary productivity plus ecosystem respiration net primary productivity minus ecosystem respiration gross primary productivity minus autotrophic respiration gross primary productivity plus ecosystem respiration gross primary productivity minus ecosystem respiration

Trophic level transfer efficiency is related to population turnover rate in agricultural pests. There are 140g/m2 of locust (herbivorous insect) per 1000g/m2 of wheat (primary producer) and 28g/m2 of cutworms (herbivorous insect) per 200g/m2 of corn (primary producer). __________ have the largest population turnover rate and __________ have the biggest impact on crops.     a. both, both b. cutworms, cutworms c. locust, cutworms d. cutworms, locust e. locust, both

If the primary producer trophic level contains 792kg of plant material, how many kg of biomass can be supported at the primary consumer or herbivore trophic level? 7.92 .792 792 79.2 O

In the context of decomposition, we can calculate a k-value. This tells us the amount of time until no substrate remains during decomposition the rate at which energy is cycled in an ecosystem the rate at which the decomposition of a substrate takes place () the rate at which decomposer populations grow the remaining mass of a substrate after a decomposition experiment

***SIMPLE ANSWER PLS***   State how biotic potential and limiting factors affect the carrying capacity.

Explain why energy flow in the ecosystem is unidirectional; while nutrients movements in the ecosystem is cyclical.

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

Answer clearly

Differentiate between primary productivity & secondary productivity?

In a temperate grassland ecosystem, to tal primary production was 12,740 g/m/yr. Annual net secondary pro duction by the herbivorous insect community was 320.5 g/m2/yr. Total net tertiary production by spiders was 22.6 g/m/yr. Is productivity biomass-based or productivity-based?
