Why is biodiversity so high in tropical rainforests yet so low in tundra and desert biomes?
satela [25.4K]

Explanation:

The tropical rainforest is made up of a dense network of trees, shrubs and vegetation.

This zone on earth is the most biodiverse on the earth surface. It receives the highest insolation of all places on earth and so radiant energy here is very high.

  • Due to this, the net productivity is very high.
  • This implies that a wide range of food is available to support the diverse organisms.
  • Also, the wet and dry seasons provides a very conducive weather for most organisms to survive.

Tundra and deserts have low precipitation and the conditions are very harsh.

Can someone tell me what's the syllabus taught in American high schools, like in 10th grade? I'm not an American student and I'm
xenn [34]

Before higher education, American students attend elementary and high school for a combined total of 12 years. These years are known as the period from first grade to twelfth grade.

At the approximate age of six, American children begin elementary school, which is exclusively called “elementary school” (elementary school). They attend this school for five or six years and then go on to high school.

High schools are made up of two programs: the first is called "middle school" or "high school" (middle school) and the second is called "high school" (high school). A diploma or certificate is awarded upon graduation from high school. Upon graduation from high school (twelfth grade), American students can go on to college or university. Studies at a college or university are known as "higher education."
