Energy Pyramid Which statement best summarizes what happens to energy as it flows through the food chain? Group of answer choices The amount of energy transferred between trophic levels decreases up the food chain The amount of energy transferred between trophic levels increases up the food chain. The amount of energy transferred between any two trophic levels of a food chain is the same. The amount of energy at each trophic level of a food chain is independent of the other levels. Flag this Question Question 410 pts Consider the food chain shown in the diagram. Food Chain 2 What conclusion about decomposers can be drawn from the diagram? Group of answer choices Decomposers are producers Decomposers form the last link in a food chain. Decomposers are primary consumers. Decomposers can also be a middle link in a food chain. Flag this Question Question 510 pts Look at the food chain below. foodwebseedsmousesnakehawk Which organism shown will get most of the available energy that is in the seeds? Group of answer choices the mouse the snake they will all get the same amount of energy from the seeds the hawk Flag this Question Question 610 pts Which describes a population depending on an abiotic factor? Group of answer choices Coral reef organisms carry out photosynthesis using the sunlight that passes through the clear water above. Squirrels eat eggs from a bird's nest. A bean plant does not grow well because it is planted where there are many weedy plants. A hawk preys on a mouse. Flag this Question Question 710 pts Which abiotic factor would have the most impact on the survival of organisms in an ecosystem? Group of answer choices temperature clouds rocks soil Flag this Question Question 810 pts How does energy enter an ecosystem? Group of answer choices energy flows from the sun to plants then to consumers energy only exists within large predators energy never enters ecosystems energy just exists Flag this Question Question 910 pts The food web in the diagram below shows interactions among organisms in a wetland. Wetland Food Web According to the diagram, which of these pairs of organisms are competing for the same food? Group of answer choices Water boatman and water plants Large fish and small fish Freshwater snails and small fish Turtle and freshwater snails Flag this Question Question 1010 pts Which situation involves mainly biotic factors? Group of answer choices Dust from a volcanic eruption blocks sunlight to Earth's surface, and as a result the weather gets colder. A drought causes crops to die, and as a result cattle go hungry. A fungus wipes out a bat population, which allows the mosquito population to increase and spread disease to people. A drop in the pH of ocean water prevents coral from growing properly, which harms the coral reef ecosystem.
