Some endangered animals are being held in captivity which provide them with food, water, toys and more species that they can play with.

Endangered animals are also being trained to protect them selves so when they are fully grown and have been put to their natural habitat, they can protect them selves from wild species and not get hunted by humans.

How do pionner species help develop soil?

Pioneer species help develop soil by breaking down rocks and organic matter through their roots and decomposition processes. They also enrich the soil with nutrients through their leaf litter and other organic material, which eventually leads to the creation of a more fertile soil for other plant species to establish and grow.


What is one way zoos help conserve natural resources?

Zoos contribute to the conservation of natural resources by participating in breeding programs for endangered species. By breeding animals in captivity, zoos help to boost populations of threatened species and reduce the pressure on their wild habitats.


How do the mountains being old trees contribute to the ecosystem's stability and biodiversity?

The old trees in the mountains provide important habitats for a variety of plant and animal species, contributing to the overall biodiversity of the ecosystem. Additionally, their deep roots help stabilize the soil, preventing erosion and maintaining the health of the ecosystem.


What type of succession takes place in an abandoned field?

Primary succession occurs in an abandoned field when plant species colonize the area where no plants previously existed. Over time, these pioneer species help to create a more stable ecosystem, allowing for the growth of more diverse plant and animal species.


What is an introduced species and how can such species affect native plants and animals?

Introduced species can either have a: positive effect, negative effect, or no effect at all. In most cases, introduced species will have no effect at all, and rarely a positive effect unless introduced for that exact reason. Ecologists usually use the "Tens Rule", which states that (on average) one out of every ten introduced species will become established; one out of every ten of those established species will become common enough to be pests. Following this rule, 90% of all introduced species will not become established in a new location for whatever reason. However, some species have a potential range that far exceeds their actual realized territory and thrive when translocated. For those that do become an invasive species, the effect on the native or indigenous species can be devastating. On almost all continents, there are invasive species that flourish in their new environment and drive competition to the max. Resources can be quickly used up and the competitive exclusion principle kicks in (two different species occupying the same geographical area cannot have the same ecological niche; one must evolve into a slightly different niche or face extinction). These invasive species are a great threat to biodiversity because they have the ability to wipe out entire species that are not prepared to cope with a new and abundant competitor. As mentioned earlier, introduced species can have a positive impact on the community. Usually these are introduced to an ecosystem in order to control another invasive species using the dynamics of trophic cascade (one trophic level suppresses another, the next level thrives, the next level is suppressed, etc). However, efforts to manipulate ecological problems hardly ever come to fruition, as 20 problems can arise from just one solution.
