  1. Deforestation

  2. Pollution

  3. Climate change

  4. All of the above


Correct Option: D
Explanation:

Mangroves are threatened by a variety of human activities, including deforestation, pollution, and climate change. Deforestation is the clearing of mangrove forests for development or agriculture. Pollution can come from a variety of sources, including industrial runoff, sewage discharge, and oil spills. Climate change is causing sea levels to rise, which is threatening mangrove forests by inundating them with saltwater.

  1. Reduce deforestation

  2. Reduce pollution

  3. Mitigate climate change

  4. All of the above


Correct Option: D
Explanation:

There are a number of things that can be done to protect mangroves. These include reducing deforestation, reducing pollution, and mitigating climate change. Reducing deforestation can be done by promoting sustainable forestry practices and by protecting mangrove forests from development. Reducing pollution can be done by reducing industrial runoff, sewage discharge, and oil spills. Mitigating climate change can be done by reducing greenhouse gas emissions.

  1. They have stilt roots.

  2. They have pneumatophores.

  3. They have salt glands.

  4. All of the above


Correct Option: D
Explanation:

Mangrove trees have a number of adaptations that allow them to survive in saline or brackish water. These adaptations include stilt roots, pneumatophores, and salt glands. Stilt roots help to anchor the trees in the soft mud of mangrove swamps. Pneumatophores are specialized roots that grow above the ground and help the trees to breathe. Salt glands help the trees to excrete excess salt.
