boreal forests and taiga 800

1. by combining your observations of the geographical location of the biomes and how many species there are in each biome, describe the general pattern followed by the distribution of species on earth.

the closer to the equator the more diversity the species but the less to the equator the less diversity of species.

1. what might be a reason (or factor) that could explain this pattern?

Explanation:

Closer to the equator, there is more sunlight, warmer temperatures, and higher precipitation, which create more favorable conditions for a greater variety of species to thrive. Away from the equator, conditions become harsher with less sunlight, colder temperatures, and lower precipitation in biomes like tundra and boreal forests, reducing species - diversity.

Answer:

Closer to the equator, there are more favorable environmental conditions (more sunlight, warmth, and precipitation) that support higher species - diversity. As one moves away from the equator, environmental conditions become less favorable, reducing species - diversity.
