If the first link in a food chain is a producer, then the second link must be a _________.
- A.
Consumer
- B.
Decomposer
- C.
Scavenger
- D.
Carnivore
Correct Answer
A. ConsumerExplanation
In a food chain, the first link is always a producer, which refers to an organism that can produce its own food through photosynthesis or chemosynthesis. The second link in the food chain must be a consumer, as consumers are organisms that obtain their energy by consuming other organisms. Consumers can be herbivores, carnivores, or omnivores, depending on their diet. Decomposers, scavengers, and carnivores can also be part of a food chain, but they are not necessarily the second link after a producer.Rate this question:

Scientists are concerned about exotic species because they
- A.
Are difficult to catch and keep alive in pet stores
- B.
Are sometimes unpleasant to look at like the bug-eyed goldfish
- C.
Do not have predators to eat them in their new ecosystems
Correct Answer
C. Do not have predators to eat them in their new ecosystemsExplanation
Exotic species are a concern for scientists because they do not have predators to eat them in their new ecosystems. This lack of natural predators allows exotic species to thrive and reproduce rapidly, leading to an imbalance in the ecosystem. They can outcompete native species for resources and disrupt the natural balance of the ecosystem, causing harm to the environment and potentially leading to the extinction of native species. Therefore, the absence of predators is a significant concern when it comes to exotic species.Rate this question:
