Question

Scientists always identify biodiversity hotspots by counting the number of endemic species.

Answer 1

Answer:

The Correct Answer is True.

Explanation:

• Biodiversity hot spots focus attention on areas where a large number of species can be protected with the least number.

The United States has passed a law in 1973 to protect its biodiversity

has three major parts:

• This law forbids citizens and the government from harming and killing of the listed species.
• This law also forbids the trade of those spices which are listed species by this law.
• United States fish and wildlife service need to maintain the official list of endangered and threatened species and maintain their recovering plan.

Answer 2

Answer:

The correct answer will be option-true.

Explanation:

Biodiversity hotspots are the regions which can be identified by a high level of endemism and high level of habitat loss. The concept of the hotspot was given by the British ecologist Norman Myers in 1988 when he observed such areas.

Since a region to be established as a biological hotspot fulfils two criteria:

1. Area should have at least 1500 unique vascular plant species found nowhere on Earth

2. Should have lost at least 70% of its native vegetation  

Therefore, a scientist identity a hotspot by counting a number of endemic species and option-true is the correct answer.
