Question

camouflage typically evolves as a result of * 1 point
predation
interspecific competition
mutualism

within an ecosystem, a tree is a * 1 point
secondary consumer
primary consumer
producer

in a hypothetical food chain consisting of grass, grasshoppers, sparrows, * 1 point
and hawks, the grasshoppers are
primary consumers
secondary consumers
secondary producers

a hypothetical community on a barren mid - atlantic island consists of two * 1 point
fish - eating seabirds (the booby and the noddy), the fungi and
microorganisms that live on the birds dung, a tick that feeds on these two
birds, a cactus, a moth that feeds on cast - off feathers, a beetle that lives on
dung organisms, and spiders that eat the other arthropods. there are no
other plants and no lichens. which of the following choices incorrectly pairs
a member of this assemblage with its position in the trophic structure?

Explanation:

• Camouflage: Camouflage helps organisms avoid being detected by predators. Predation is a strong selective pressure. Organisms with better camouflage are more likely to survive and reproduce.
• Tree in an ecosystem: Trees are autotrophs. They produce organic matter (glucose) through photosynthesis. Producers are organisms that can make their own food, which fits trees.
• Grasshoppers in the food - chain: Grass is a producer. Grasshoppers eat grass. Primary consumers are organisms that eat producers.

Answer:

• Camouflage typically evolves as a result of: predation
• Within an ecosystem, a tree is a: producer
• In a hypothetical food chain consisting of grass, grasshoppers, sparrows, and hawks, the grasshoppers are: primary consumers
