What is benthic macroinvertebrate?

Answer 1

Macro-invertebrates are small organisms that do not have a backbone. They are all insects, arthropods, arachnids. Invertebrates means; In, not and vertebrate, vertebrae (backbone) essentially meaning, no vertebrae. These organisms instead have an exoskeleton, a hard shell covering their body to protect their organs. The exoskeleton is made of chiton (protein) that has. Not all macro invertebrates have an exoskeleton some, like the jellyfish, do not

Answer 2

Benthic means "living on the bottom"

Invertebrate means "Without a spine"

Macro means (in this context) "Can be seen with the naked eye"

So a Benthic Macroinvertebrate is a spineless organism large enough to see with the naked eye that lives on the bottom of a body of water (such as a stream).

Answer 3

benthic - bottom-dwelling

macro - able to be seen by the naked eye

invertebrate - animal (insect) with no backbone

A benthic macroinvertebrate is a fresh water bottom-dwelling insect with no backbone.

Answer 4

Benthic macroinvertebrates are small organisms without a backbone that live on the bottom of aquatic ecosystems such as rivers, lakes, and streams. They play a significant role in the food web and serve as indicators of water quality because their presence and abundance reflect the health of the ecosystem. Examples include insect larvae, mollusks, crustaceans, and worms.

Answer 5

they are indicaters of the river`s health and can be food for other living creatures that are bigger than them.
