Which of the following correctly pairs labels of animals with the way they feed?
a. filter feeders – strain food from water
b. carnivores – eat plants
c. parasites – other animals and in turn are rewarded with food
d. herbivores – eat bits of decaying matter

The correct answer would be A. Filter feeders – strain food from water.

Filter feeding is a type of food acquirement in which suspended food material and/or small organisms are strained randomly from the water.  

It is accomplished by passing water through the specialized filtering structure.

Examples of filter feeder may include krill, clams, baleen whale, sponges, and many fishes. Few birds like a flamingo and some species of duck also practice filter feeding.

These organisms are considered as ecosystem engineers as they play a crucial role in cleaning water.

A.  Filter feeders – strain food from water

Explanation:

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
