Question

Which of the following is not a way humans have directly impacted coral reefs? a. overfishing b. tourism c. algae farming d. agriculture

Answer 1

c. algae farming

Step-by-step explanation:

Human influence on coral reefs is vital. Coral reefs are fading throughout the world. Damaging actions comprise coral mining, pollution, overfishing, amusement fishing, the digging of waterways and entrance into islands and bays. Other uncertainties include illness, devastating fishing systems and warming oceans.

A coral reef is an underwater ecosystem described by reef-building corals. Reefs are composed of groups of coral polyps kept collectively by calcium carbonate. Maximum coral reefs are developed of stony corals, whose polyps gather in combinations.

Answer 2

The correct answer is option c, that is, algae farming.

The algae farming is not one of the factors, which has taken part directly to the destruction of the coral reefs. The algae farming is being conducted at special centers, and in strictly monitored conditions in the sea, near the shores.

The factors that are affecting the coral reefs population are an unawareness of the tourists, overfishing, and use of heavy herbicides, pesticides, fungicides in agriculture, which get into the water and end up in the sea leading to the destruction of coral reefs due to change in temperature of the water.
