Hello students, the factor that has greatest effect on species diversity in an area besides the number of species is habitat heterogeneity.
00:11
Habitat heterogeneity refers to variety and complexity of different habitats within an ecosystem or a geographical area.
00:20
First, habitat diversity.
00:23
In areas with wide range of different habitats such as forests, grasslands, wetlands, mountains, rivers, and lakes, there are more opportunities for different species to find suitable environments.
00:37
Each habitat type provides specific resources, conditions, and niches that support different species with varied adaptations.
00:47
Next is resource availability.
00:49
Habitat heterogeneity often means a greater availability of resources like food, water, and shelter.
00:55
Different habitats can offer variety of food sources which can support different species with specific dietary requirements.
01:04
Next is niche partitioning.
01:06
In a heterogeneous environment, different species can occupy different niches with different habitats...
