-Format: Multiple-choice / Flashcard

Question 1: producers (mainly plant life)

Answer:

also known as autotrophs, they make their own food via photosynthesis

Question 2: decomposers (bacteria and fungi)

Answer:

also known as saprotrophs, they break down organic matter and release minerals back into the soil

Question 3: primary consumers

Answer:

aslo known as herbivores, the subsist on producers, such as plants. Examples include grasshoppers, deer, cows, squirrels, and rabbits.

Question 4: ecosystem

Answer:

a system made up of a community of animals, plants, and other organisms as well as the abiotic (non-living) aspects of its environment

Question 5: ecology

Answer:

ecology is the study of the interrelationships between organisms and their physical surroundings

Question 6: the food chain

Answer:

the various populations within a community fall into one of several roles in the food chain

Question 7: biosphere

Answer:

the zone of planet Earth where life naturally occurs, including land, water and air, extending from the deep crust to the lower atmosphere

Question 8: consumers (most animals)

Answer:

also known as heterotrophs, refers to animals that consume other organisms to survive. Consumers are

divided into three types: primary, secondary, and tertiary

Question 9: community

Answer:

the collection of all ecologically connected species in an area

Question 10: biome

Answer:

a major life zone of interrelated species bound together by similar climate, vegetation, and animal life

Question 11: tertiary consumers

Answer:

also known as top carnivores, they are capable of eating secondary consumers. Many tertiary consumers are also omnivores, meaning they also consume primary consumers and occasionally producers as well

Question 12: ecosystems, communities, and populations

Answer:

the difference between biomes and ecosystems is that biomes need merely to share similar characteristics, whereas ecosystems must be contiguous and contain organisms that ly interact together. An ecosystem can be large or small, and can include both pristine and highly developed areas.

Question 13: scavengers (many insects and certain vertebrates, such as vultures and jackals)

Answer:

these are animals that function like decomposers, by consuming refuse and decaying organic matter, especially carrion, or decaying flesh. Similar organisms called detritivores consume the small pieces of decaying organic matter called detritus that are too small form most scavengers to want.

Question 14: population

Answer:

a group of organisms of the same species living in the same region

Question 15: secondary consumers

Answer:

also known as carnivores or predators, they subsist mainly on primary consumers. Examples include lions, wolves, and sharks. Some secondary consumers are also omnivores, meaning the consume producers and consumers
