- Efficiency of energy transfers in aquatic ecosystem is typically higher than in land ecosystems because ______. a. aquatic food webs include more endotherms b. algae do not make lignin c. primary production cannot occur in water d. all of the aboveThe loss of an apex consumer would impact which trophic level of a food web? primary producers primary consumers secondary consumers all of the aboveIn a pond ecosystem, mosquito larvae feed on photosynthetic algae. Other larvae, such as dragonfly larvae, feed on the mosquito larvae. The dragonfly larvae are, in turn, consumed by fish, whichcan be preyed upon by raccoons.Which organism is a primary consumer in this ecosystem? 1.Mosquito larvae2. Fish3. Algae4. Dragonfly larvae
- 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 shape of an ecological pyramid, with each successive layer being smaller than the one below it, can be explained most readily by:a. the first law of thermodynamicsb. inefficient geochemical cyclesc. the second law of thermodynamicsd. industrializationFind the Flaw Biomagnification in how the amount of toxin in an organism will increase as you move up a food chain. For example, a plant might only have a little toxin but an herbivore eats a lot of plants. So, now the herbivore has a medium amount of toxin. A carnivore eats a lot of herbivores and now the carnivore has a high amount of toxin and is sick. The water cycle has five important processes. Evaporation which is water turning into vapor. Condensation and precipitation refer to water vapor turning into liquid or solid water. Subsurface water flow feeds rivers and streams. Surface runoff is water from precipitation gathering in streams. Streamflow moves water from mountains to oceans. The nitrogen cycle has four steps. Denitrification is where bacteria take nitrogen from the atmosphere and convert it into a form that is usable by other biological systems. Ammonification is where nitrogenous waste is converted into ammonia. Nitrification is where ammonia is converted into…
- estimate the total primary production in the oceans (in million metric tons carbon) using the following information - 92% of oceans are open ocen with an average productivity of 125 gC/m2/yr - 8% of the oceans are coastal, with an average productivity of 2,000 gC/m2/yr - remember a metric ton is 1,000 KgEarth 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)?WRITE ABOUT A THEME: Energy and MatterDecomposition typically occurs quickly in moist tropicalforests. However, waterlogging in the soil of some moisttropical forests results over time in a buildup of organicmatter called “peat.” In a short essay (100–150 words), discussthe relationship of net primary production, net ecosystemproduction, and decomposition for such an ecosystem. AreNPP and NEP likely to be positive? What do you think wouldhappen to NEP if a landowner drained the water from atropical peatland, exposing the organic matter to air?
- Scientists at the Global Footprint Network calculate the energycomponent of our ecological footprint by estimating the amountof ecologically productive land and sea required to absorb thecarbon released from fossil fuel combustion. This translates into4.9 ha of the average American’s 7.2-ha ecological footprint.Another way to think about our footprint, however, is to estimatehow much land would be needed to grow biomass with anenergy content equal to that of the fossil fuel we burn.Assume that you are an average American who burns about6.3 metric tons of oil-equivalent in fossil fuels each year andthat average terrestrial net primary productivity (p. 32) can beexpressedas 0.0037 metric tons/ha/year. Calculate how manyhectares of land it would take to supply our fuel use by presentdayphotosynthetic production. Compare the energy component of your ecological footprintcalculated in this way with the 4.9 ha calculated usingthe method of the Global Footprint Network. Explainwhy results from…Find the flaws! Energy in a terrestrial ecosystem moves from the sun, to producer, to primary consumer, to secondary consumer, ending in a tertiary consumer. Producers are heterotrophs and consumers are autotrophs. Biomagnification in how the amount of toxin in an organism will increase as you move up a food chain. For example, a plant might only have a little toxin but an herbivore eats a lot of plants. So, now the herbivore has a medium amount of toxin. A carnivore eats a lot of herbivores and now the carnivore has a high amount of toxin and is sick. The water cycle has five important processes. Evaporation which is water turning into vapor. Condensation and precipitation refer to water vapor turning into liquid or solid water. Subsurface water flow feeds rivers and streams. Surface runoff is water from precipitation gathering in streams. Streamflow moves water from mountains to oceans. Carbon can cycle either quickly or slowly. “Fast” carbon cycling happens in biology.…1.) Which of the food chains below fit the food web in the diagram? a).
