a hypothetical community on a barren mid - atlantic island consists of two
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?
fungi, detritivores

Explanation:

• For "Within an ecosystem, a tree is a":
• Producers are organisms that can make their own food through photosynthesis. Trees use sunlight, water, and carbon dioxide to produce glucose (food). Secondary consumers eat primary consumers, and primary consumers eat producers. Since trees make their own food, they are producers.
• For "In a hypothetical food chain consisting of grass, grasshoppers, sparrows, and hawks, the grasshoppers are":
• In a food chain, primary consumers eat producers. Grass is a producer (makes its own food via photosynthesis). Grasshoppers eat grass, so they are primary consumers. Secondary consumers eat primary consumers (e.g., sparrows eat grasshoppers). There is no such thing as a secondary producer in a typical food - chain context.

Answer:

• For "Within an ecosystem, a tree is a": producer.
• For "In a hypothetical food chain consisting of grass, grasshoppers, sparrows, and hawks, the grasshoppers are": primary consumers.
