A. It reduces competition among species so that they can co - exist, which helps maintain the balance of the ecosystem B. It allows species to have more space to reproduce, which is good for increasing biodiver

How does an ecosystem（生态系统）work？What makes the populations of different species the way they are？Why are there so many flies and so few wolves？To find an answer，scientists have built mathematical models of food webs，noting who eats whom and how much each one eats. 一个生态系统是...
Spatial HeterogeneitySpatial variation contributes to functional and species diversity (a greater variety of habitats that can support different species) while also ensuring the complexity and diversity of ecological processes and functions (which deliver ecosystem services) are maintained. Channelizing rivers...
Conservation biologists have long been concerned that species extinction could have significant consequences for the stability of entire ecosystems—groups of interacting organisms and the physical environment that they inhabit. An ecosystem could survive the loss of some species, but if enough species wer...

Biomes are complex mixtures of a large number of similar ecosystem types which share a similar physiognomy (vegetation structure) and climate but do not necessarily share the same species. Indeed, one of the strengths of the biome approach is that ecosystems with different species compositions, ...
Every species has different requirements for tank size, food and the chemical conditions of the environment it wants to live in. When creating an ecosystem in a bottle with plants and fish, all of the environmental and social needs must be taken into account. ...
