B. Understands relationships between organisms and the environment and describes ways that living organisms depend on each other and on the environment to meet their basic needs.
C. Identifies organisms, populations or species with similar needs and analyzes how they compete with one another for resources.
D. Analyzes the interrelationships and interdependence among producers, consumers and decomposers in an ecosystem (e.g., food webs, food chains, competition, predation).
E. Identifies factors that influence the size and growth of populations in an ecosystem.

While exploring a lake in Argentina, Laguna del Diamante (Diamond Lake), scientists found rocks covered with mats made of photosynthetic microbes. Flamingos in the area filter the nutrient-rich microbes by pumping the lakewater through their bill. What is the relationship between the photosynthetic microbes and the flamingos in the Laguna del Diamante ecosystem?

A  The microbes are parasites, and the flamingos are hosts.

B  The microbes are carnivores, and the flamingos are predators.

C  The microbes are herbivores, and the flamingos are carnivores.

D  The microbes are producers, and the flamingos are consumers.

Answer: D is correct - Neither the alligator nor the heron is well-adapted to survive long periods in an extremely cold, dry environment such as the tundra.

Answer: H is correct - Barracudas are predators of other fish which are other living elements of the environment.

Answer: B is correct - Strawberries and earthworms are living parts of the environment. 

# data[].attributes.attachment_caption
Answer: C is correct - Grasses are producers, which capture energy from the sun and make food for consumers. 

# data[].attributes.attachment_caption
Answer: F is correct - Food webs provide descriptions of feeding relationships among organisms in a community.  An organism identified at the base of an arrow is an organism that is eaten (the food source), while the organism at the point of an arrow is the consumer of that organism. In this food web, both the hawks and snakes eat mice.

Answer: D is correct - The grass is a living component of the ecosystem, and the water is a nonliving component.

Answer: C is correct - Water and rocks are nonliving parts of the frog's habitat.

Answer: Bird is consumer, Mushroom is decomposer, Caterpillar is consumer, Parsley is producer. The bird is a consumer because it feeds on the caterpillar and cannot make its food. The mushroom is a decomposer because it breaks down decaying organic matter in the soil from the parsley plant. The caterpillar is a consumer because it feeds on the plant and cannot make its food. The parsley is a producer because it is a plant and makes its own food.

Answer: D is correct - The carnivores in the desert food web are lizards, scorpions, snakes, foxes, and hawks.

Answer: B is correct - When the land is overgrazed, there are fewer plants and, therefore,
fewer roots. With fewer roots in the soil, it is more likely that soil
erosion will occur.

Answer: A is correct - Sedimentary rocks that formed underwater can be uplifted to produce
mountains.
