Which of the following describes a relationship of predator-prey?

oxpecker birds eat parasitic ticks off the backs of zebras

a moray eel eats a fish swimming by

a tick attaches itself to the inside leg of a deer

birds feed off the insects that are stirred up from the grasses as cattle move through

Hello,

The correct answer option is B. A moray eel eats a fish swimming by

Explanation:

A Moray eel is carnivore and feeds on  fish, octopuses or crabs. In this case the Moray eel is the predator whereas the fish is the prey.In a predator-prey relationship, one of the species will be hunted for food by the other species.This relationship is important because it can help to slow down the spread of diseases.

Best of Luck!

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.

well the answer is 2!
