bio 3.3

Question 1

producer

Answer 1

person or organism that creates and supplies goods or services, or that makes its own food

Question 2

primary consumers

Answer 2

consumes producers

Question 3

secondary producers

Answer 3

consumes primary consumers and or decomposers

Question 4

tertiary consumer

Answer 4

consumes secondary consumer

Question 5

autotroph vs herterotroph

Answer 5

Autotrophs produce their own food from inorganic sources (like sunlight or chemicals), serving as the base of food chains, while heterotrophs cannot make their own food and must consume other organisms for energy and nutrients

Question 6

Herbivore vs. Omnivore vs. Carnivore vs. Detritivore

Answer 6

Herbivores primarily consume plants, carnivores eat only meat, omnivores consume both plants and meat, and detritivores feed on dead organic matter, such as dead plants or animals, to obtain nutrients

Question 7

Describe differences between food web and trophic cascade diagrams

Answer 7

A food web shows the multiple, complex feeding relationships and energy flow within an entire community, while a trophic cascade diagram illustrates a specific ecological phenomenon where the addition or removal of a top predator causes ripple effects down the food chain, altering the relative populations and structure of other trophic levels

Question 8

Identify trophic levels of organisms in a food web

Answer 8

Producers (Trophic Level 1), which create their own food, followed by Primary Consumers (Trophic Level 2), which eat producers (herbivores). Secondary Consumers (Trophic Level 3) eat primary consumers, Tertiary Consumers (Trophic Level 4) eat secondary consumers, and so on, with the levels continuing up to apex predators

Question 9

Read and make predictions using a trophic cascade model

Answer 9

Classic Examples
Sea otters: Sea otters control urchin populations, which allows kelp forests to thrive
