There is no answer to that question, I'm sorry. New species are found all the time, so it is impossible to keep on track of how many animals have scientists found. They think, that probably over 90 % of all world's species are not yet found.
The term is biodiversity. High biodiversity means a large number of different species in an ecosystem. An ecosystem with many different species is less likely to be disrupted by environmental changes.

biodiversity. Biodiversity refers to the variety of different species and their interactions within an ecosystem. A high level of biodiversity indicates a healthy and balanced ecosystem that can better withstand environmental changes or disturbances.
A community is the level of organization defined as a group of different species that live together in a single ecosystem. It consists of all the populations of different species interacting and coexisting in a specific area.
There are a number of different types of species of organisms in an ecosystem in order for it to be functional and stable. Different organisms add species diversity which increases the stability of the ecosystem. Eg. the ecosystem such as a forest can quickly regenerate after a natural disturbance such as a fire.
This depends on which alpine ecosystem it is, the climate, and the predators within it. Different alpine ecosystems have quite varied animal populations.
Biodiversity refers to the variety and variability of life forms within an ecosystem or a community. It encompasses different species, genetic diversity, and ecosystem diversity.
A biological population consists of all one species instead of many species.
There are several ways to measure biodiversity in an ecosystem, including species richness (the number of different species present), species evenness (how evenly distributed the species are), and species abundance (the number of individuals of each species). Other methods include genetic diversity (variety of genes within a population) and ecosystem diversity (variety of habitats within an ecosystem).
Different species in an ecosystem occupy different niches, or roles, that allow them to coexist without directly competing for the same resources. This diversity of species helps stabilize the ecosystem by ensuring that no single species becomes too dominant. Additionally, many species have evolved specialized traits that allow them to efficiently use specific resources, further reducing competition.
