| Question | Answer |
|---|---|
| is an undesirable condition where the number of existing human population exceeds the carrying capacity of earth | overpopulation |
| in what age or time human population fluctuates | modern times |
| the global population is projected to reach ________ on november 15, 2022 | 8 billion |
| human overpopulation is caused by number of factors | decline in death rate, better medical facilities, progress in food production, technological advancement in fertility treatment, lack of family planning, migration, urban concentration |
| effects of natural resources | exhaustion of natural resources, environmental degradation |
| is the variety and variability of life on earth. __________________ is typically a measure of variation at the genetics, species and ecosystem level | biodiversity |
| three main components of biodiversity | genetic diversity, species diversity, ecosystem diversity |
| in a vole population | genetic diversity |
| in a coastal redwood ecosystem | species diversity |
| across the landscape of an entire region | ecosystem diversity |
| is the termination of a kind of organism or of a group of kinds, usually a species | extinction |
| is a natural phenomenon that has been occurring since life first evolved | extinction |
| a species that is in danger throughout all or a significant portion of its habitat | endangered |
| species that is likely to become endangered in the foreseeable future | threatened |
| three threats to biodiversity | Habitat Loss, Introduced species, Overexploitation |
| is the greatest threat to biodiversity throughout the biosphere | human alteration |
| occurs when natural habitats are no longer able to support the species present, resulting in the displacement or destruction of its biodiversity. | Habitat destruction |
| may remain intact, but it's degraded state may render it incapable of functioning properly and lead to species extinction or migration | Habitat Degradation |
| the process during which a large expanse of habitat is transformed into a number of smaller patches of smaller total area isolated from each other by a matrix of habitats unlike the original. | Habitat Fragmentation |
| Alien species, exotic species, foreign species, non-indigenous species, or non-native species | introduced species |
| gain a foothold in a new habitat usually disrupt their adopted community. | introduced species |
| n is human harvesting of wild plants or animals at rates exceeding the ability of populations of those species to rebound | Overexploitation |
| the penguin-like bird of the north, was hunted for its feathers, meat, fat and oil | great auk |
| The only parrot species native to the eastern United States, was hunted for crop protection and its feathers | carolina parakeet |
| is the introduction of contaminants into the natural environment that cause adverse change | pollution |
| t is a waste material that pollutes air, water, or soil, can be either foreign substances/energies or naturally occurring contaminants. | pollutant |
| is protection, upliftment and scientific management of biodiversity so as to maintain it at its threshold level and derive sustainable benefits for the present and future generation | biodiversity conservation |
| types of biodiversity conservation methods | in-situ conservation, ex-situ conservation |
| refers to the conservation of species in their natural ecosystem or natural habitat | in-situ conservation |
| The conservation of biodiversity outside of their natural environments or ecosystems | ex-situ conservation |
