Most extinctions are believed to occur as background extinctions because they result from gradual changes in environmental conditions, competition, and ecological shifts rather than catastrophic events. These slow processes allow species to gradually decline over time due to factors like habitat loss, climate change, and resource depletion. Background extinctions typically reflect the normal turnover of species, where weaker or less adaptable organisms are outcompeted or unable to survive in changing conditions. This contrasts with mass extinctions, which are sudden and dramatic, affecting a wide range of species simultaneously.
Tropical rain forest
Sudden changes in environmental conditions.
Most hurricanes in the United States occur in the state of Florida. This is because of its geographical location and warm waters, which provide favorable conditions for hurricane formation and development.
They occur in the tropical convergence zone
Well, there have been several "great extinctions" in earth's history, but the most recent one was the Cretaceous-Tertiary event, ending the Cretaceous. That was c. 65 million years ago.
Most extinctions occur as background extinctions because they are longer time periods unlike the shorter mass extinctions which there were only two in the Paleozoic era, the Ordovician mass extinction, and the Permian/Triassic extinction in which 95% of all marine animals became extinct
invertabates are the animals with the most extinctions
Tropical rain forest
climate change
Sudden changes in environmental conditions.
in solids i think
I think that habitat loss and destruction is probably responsible for the highest number of extinctions. Other major causes can include pollution, overhunting/poaching, and global warming.
well, i think that most flooding ocurrs in basments in peoples houses
i think it is at an intersection. i have it on my traffic school online thing. hope it helped.. =]
I think it's a synthetic reaction
This is an interesting question and not one that is easily answered. In terms of the entire history of life on earth the groups of individual species that have been around the longest would have experienced the most extinctions. The more complex the animal the fewer organisms produced and therefore the fewer species available for extinction. This makes various unicelluar organisms (animal, plant and bacterial) subject to the most extinctions. Even though several mass extinctions have occurred, the focus is primarily on the larger identifiable organisms of the time, (Dinosaurs for example), especially those that have a fossil record proving they existed. This places the focus on complex plants and animals. Focus is often on man caused extinctions as well...which are, on the whole, a very small number in the grand scheme of the history of life on Earth. The primary concept to remember is that: Extinction is the rule, NOT the exception.
Africa during to the levels of environmental issues the eating,killing and really poaching yeah!!!
