These organisms can be Fauna‚ Flora (Flora and Fauna refer to plant and wildlife‚ respectively)‚ a fungus or a bacterium. However‚ not all introduced species are invasive‚ but invasive Fauna and Flora‚ have been said to be the 2nd greatest threat to biodiversity post habitat loss. In his book‚ Invasive Species in a Changing World‚ Richard J. Hobbs (2013)

expand and reproduce on their own (Forest Management). This means that they have the ability to compete with native species and other native plant communities. Non-native invasive species affect natural ecosystems negatively by completely taking over all other plants. This can unbalance the ecosystem and harm animals as well as nearby plants. They can also spread exotic diseases to other plant life. 46% of the federally listed threatened and endangered species of plants in the United States are considered

Concern of Our Eco System The variety of life on Earth‚ its biological diversity is commonly referred to as biodiversity. The number of species of plants‚ animals‚ and microorganisms‚ the enormous diversity of genes in these species‚ the different ecosystems on the planet‚ such as deserts‚ rainforests and coral reefs are all part of a biologically diverse Earth. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any approach. Almost all cultures

FRQ: Ecology Question Ecological succession from a pioneer community to a climax community is an easy process to understand once you know each step. Ecological succession is the transition in the species composition of a biological community‚ often following ecological disturbance of the community. There are two types of ecological succession‚ primary and secondary. Primary succession is the establishment of a biological community in an area virtually barren of life‚ where there were originally
