- A desert ecosystem includes grasses, mice, snakes, and hawks. As you move up the energy pyramid of this ecosystem, each level has energy *blank* than the one below.In 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.How many different organisms in this ecosystem get their energy from the food they consume?1. One2.TWO3.Three4.Foursupport or refute the following statements based on what you learned about energy flow, biogeochemical cycling, decomposition, trophic levels, and keystone species. You may add a diagram or illustration to support your answer. Shark fin soup can cause the collapse of coral reef ecosystem
- Which statement about energy is false?Group of answer choices It includes work, plus anything that can be transformed into work. In chemical form, it is passed up the food chain, along with nutrients. It moves between the living and nonliving world. Because energy is neither created nor destroyed, ecosystems can run indefinitely without any input energy. Some ecosystems can function independent of the energy of sunlight.Energy flow or calorific flow in an ecosystem is described as an open system. Critically explain what this means with real life example.At which level of an energy pyramid would you expect to find the largest population of organisms? a primary consumers b producers c secondary consumers d tertiary consumers
- Why is energy flow is important in an ecosystemUsing organisms that live in San Diego County, draw your own food CHAIN here. Use arrows to show which way energy is flowing. Label your drawingsWhich statement best describes conditions that would result in net global cooling? a) Solar energy entering Earth’s atmosphere equals energy leaving. b) Solar energy entering Earth’s atmosphere exceeds energy leaving. c) Solar energy entering Earth’s atmosphere is less than energy leaving. d) Energy flows through ecosystems, with some energy lost at every transition. e) Removing trees (deforestation) would remove insulation from Earth’s surface resulting in heat loss.
- Based off the graph answer the question. Right now, a lot of biofuel is made from corn grain. If society were to switch to biofuels made from grass, which of the following statements correctly states the overall difference in energy input per hectare of crop? A. Society would use about the same amount of energy in crop growth. B. Society would use about 90% more energy per hectare of crop. C. Society would use about 90% less energy per hectare of crop.We humans are responsible for climate change primarily because we have greatly disrupted Group of answer choices trophic-level interactions the carbon cycle nutrient subsidies the 2nd law of thermodynamics energy flow through ecosystemsAs a general rule, for each jump up in trophic level, about how much does the available energy drop? Group of answer choices practically 100 percent 90 percent 10 percent 30 percent 50 percent
