In a temperate grassland ecosystem, total primary production was 12,740 g/m/yr. Annual net secondary production by the herbivorous insect community was 320.5 g/m'/yr. Total net tertiary production by spiders was 22.6 g/m²/yr. Calculate the trophic efficiency from the first trophic level to the third trophic level.

Questiion: A given ecosystem has the following amounts of energy available at each trophic level: Primary producers: 3,000 gC/m2/day; Primary consumers: 450 gC/m2/day; Secondary consumers: 45 gC/m2/day; Tertiary consumers: 2.25 gC/m2/day. Does this ecosystem follow Lindeman’s Law for ecological efficiency? A- No, the average efficiency is 20% B- Yes, the average efficiency is 20% C- Yes, the average efficiency is 10% D- No, the average efficiency is 10%
5. Trophic level transfer efficiency is related to population turnover rate in agricultural pests. There are 15g/m2 of locust (herbivorous insect) per 1000g/m2 of wheat (primary producer) and 4g/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. locust, both b. locust, cutworms c. cutworms, cutworms d. both, both e. cutworms, locust
Net primary production per unit area is likely to be highest in which of the following ecosystems?a. grasslandsb. desertsc. temperate deciduous forestsd. tropical rain forests
EcosystemA hasprimary production of 1000 g C /m2/yr and ecological efficiency of 10%. Ecosystem B has primary production of 300 g C /m2/yr and an ecological efficiency of 25%. a.Which ecosystem will have more production at thesecondary consumer (carnivore) trophic level? b.Which ecosystem is more likely to support an endothermic primary consumer (herbivore)? c.If atrophic level requires at least 1 gC/m2/yr in order to exist, how many trophic levels can each of these ecosystems support?d.Given your answer to part c, which do you thinkhas a larger impact on the energy available at upper trophic levels: primary productivity or efficiency of energy movement across trophic levels?
In an ocean ecosystem, the biomass of an algal community is approximately 3000 kilograms. It can support a food chain up to 4 levels. Considering an efficiency at an average of 10% in passing on energy from one trophic level to the next level, how much biomass of the fourth trophic level can be maintained.
Earth has a total of 11.9 billion gha of productive land. How many people could Earth supportsustainably if the average ecological footprint were 8 gha per person (as in the United States)?
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
What trophic level (i.e level 1 or 2, etc)contains the greatest biomass in most ecosystems? Explain why this occurs.
An estimated 1000 kg of plant plankton are needed to produce 100 kg of animal plankton. The animal plankton is in turned consumed by 10 kg of fish, the amount needed by a person to gain 1 kg of body mass. i) explain why the amount of biomass declines at each successive trophic level.
The average efficiency of energy transfer between trophic levels is 10%. Use this efficiency to determine how much phytoplankton mass is required to add just 1 gram (0.04 ounce) of new mass to a killer whale, which is a third-level or top carnivore. Create a diagram that summarizes the different trophic levels and the relative size and abundance of organisms at each level. How would your answer change if the efficiency were half the average rate? Twice the average rate?
Availability of energy is less for entities at higher trophic levels.Why?
Which of the following statements is supported by the results of studies at the Hubbard Brook Experimental Forest? a. Most of the energy captured by primary producers is lostbefore it reaches the highest trophic level in an ecosystem. b. Deforested watersheds experience significantly less runoffthan undisturbed watersheds. c. Deforested watersheds lose more calcium and nitrogen inrunoff than undisturbed watersheds. d. Nutrients generally move through biogeochemical cycles veryquickly. e. Deforested watersheds generally receive more rainfall thanundisturbed watersheds.
