1. B. They have the same niche in different habitats.
Both the tahrs and the mountain goats are two species that occupy the same niche known as the alpine vegetation zone. However, they live in different habitats: the tahrs in the Himalaya Mountains and the Mountain goats in Yellowstone National Park.
2. B. lappet-faced vultures only
The lappet-faced vultures is a very large Old World vulture that has a scavenger lifestyle, feeding mostly on animal carcasses.
Fennec foxes are nocturnal hunters (secondary consumers), fat sand rats have a typical rodent diet (primary consumers) and barrel cacti are primary producers.
3. D. northern cardinals – (is it the same habitat as the one in the northern cardinal picture?)
The bird in the attached picture is a northern cardinal. They live in woodlands, shrublands, wetlands and gardens from southern Canada in the north, to Mexico, Belize, Guatemala, etc. in the south.
4. B. builds cup-shaped nests in small trees
The northern cardinal is a mid-sized songbird that builds cup-shaped nests from twigs, grapevine bark, grasses etc. in small trees.
5. D. ground of temperate deciduous forest
Black bears are primarily found in forested areas with thick ground vegetation. These provide an abundance of fruits, nuts, roots etc.
6. B. canopy in a rainforest
The two-toed sloth can be found in the rainforests of Central and South America.
7. B. a unique environment in which an organism lives
A habitat is the natural environment in which a population or species normally lives.
8. A. only one
Due to the Gause’s Principle, two species or populations that compete for the exact same resources (niche) cannot coexist because one is more likely to be more successful. Although sometimes it may appear different, upon closer study it has been shown that two apparently coexisting species occupy slightly different niches.
