What happens to the solar energy absorbed by plants during photosynthesis?
a) It is recycled by plants and returned to the atmosphere. b) It is converted into carbon dioxide and glucose. c) It is stored as heat within the plant for cellular functions. d) It is transformed into chemical energy.
Which best describes the process of photosynthesis?
a) Sunlight, CO2, and water enter the leaf ; oxygen leaves the leaf; glucose stays in the plant. b) Sunlight, water and glucose enter the leaf and CO2 and oxygen leave the leaf. c) Sunlight, oxygen and glucose enter the leaf and CO2 and water leave the leaf. d) Sunlght, oxygen, and CO2 enter the leaf; water leaves the leaf and glucose stays in the plant.
Which of the following organisms can undergo photosynthesis?
a) animals and plants b) animals and fungi c) plants and fungi d) plants only
Which of the following are producers?
a) cactus and sagebrush b) hawks and coyotes c) ants and tarantulas d) rats and snakes
When energy is passing through a food web, some of the energy is lost. How much of the energy is passed from one level to the next?
a) 1% b) 10% c) 50% d) 90%
In a desert ecosystem how would a large decrease in the number of rats impact the food web?
a) There will be an increase in the number of ants, tarantulas and snakes. b) There will be an increase in the number of snakes, coyotes, and hawks. c) There will be a decrease in the number of snakes, coyotes, and hawks. d) There will be a decrease in the number of cacti and sagebrush plants.
Which of these is not a consumer?
a) plants b) fish c) beetles d) pelicans
What is the concept being demonstrated in an energy pyramid?
a) The energy pyramid is a model that illustrates the transformation of energy between all organisms in an ecosystem. b) An organism that appears at the top of the pyramid always is the largest in size compared to other organisms found below it. c) The pyramid explains how energy flows from top to bottom because an organism at the top is larger and needs more energy. d) An energy pyramid shows the ratio of organisms needed at each trophic level in order to support the energy transformation.H
The process shown here produces chemical energy. What is missing? carbon dioxide + water ---- glucose + oxygen
a) Light energy on the right side of the equation because light is produced from this reaction. b) Light energy on the left side of the equation because light is necessary for the reaction to occur. c) Electrical energy on the right side of the equation because electricity is produced from this reaction. d) Electrical energy on the left side of the equation because electricity is needed for this reaction to occur.
Leftover food can be put into compost bins, and after a few weeks turns into soil. What is occurring in the compost bin?
a) Decaying causes the food to become cold. b) Energy stays in the food. c) Matter is recycled through decay. d) New elements are formed.
Which ecosystem would be more likely to survive if a disease killed the grasses?
a) a forest ecosystem, because most of the animals can eat other organisms b) a grassland ecosystem, because several predators compete for food c) a forest ecosystem, because it has more top predators d) a grassland ecosystem, because it has many herbivores
In an energy pyramid, which consumers would have the greatest amount of energy captured by the producers in their food chains?
a) primary consumers b) secondary consumers c) tertiary consumers d) quaternary consumers
What kind of energy is necessary to initiate the process of photosynthesis?
a) radiant b) heat c) electrical d) wind
