Question

4.1 energy, producers, and consumers
completion
for each missing word, circle the choice that correctly completes the sentence.

1. gerald is studying the plants and animals of a meadow. he classifies the grasses and clover as (producer / consumers / decomposers / heterotrophs) because they make their own food through the process of (chemosynthesis / decomposition / photosynthesis / regurgitation). he classifies insects that feed on the clover as (carnivores / detritivores / herbivores / omnivores) because he thinks they eat only plant matter, not animal matter.

classify
write a letter on each line to classify the organism.

1. identify each type of organism as either a primary producer or a consumer. write p for a primary producer, and c for a consumer.

plants
animals
fungi
bacteria that perform chemosynthesis
bacteria that perform photosynthesis
multiple choice
write the letter that best answers the question or completes the statement on the line provided.

1. which statement describes all primary producers?

a. all make energy - rich compounds that can be used by other organisms.
b. all make their own food using the energy of compounds in the environment.
c. all take in energy - rich compounds that were made by other organisms.
d. all make their own food using the energy of sunlight.

Explanation:

1. Grasses and clover are producers as they make food via photosynthesis. Insects eating only plant - matter are herbivores.
2. Plants are primary producers (P), animals are consumers (C), fungi are decomposers (neither P nor C in this context strictly), bacteria that perform chemosynthesis are primary producers (P), bacteria that perform photosynthesis are primary producers (P).
3. Primary producers make energy - rich compounds usable by other organisms. Some use sunlight (photosynthesis) and some use chemical energy (chemosynthesis).

Answer:

1. producer; photosynthesis; herbivores
2. P; C; (not applicable); P; P
3. a.
