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.
What else can I help you with?
Where are most extinctions occurring today?
Tropical rain forest
Past mass extinctions most likely occurred as a result what?
Sudden changes in environmental conditions.
What state do most hurricanes occur?
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.
Where do most hurricane occur the most and why?
They occur in the tropical convergence zone
What age of geologic time ended with the great extinction?
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.
Why do you think most extinction's occur as background extinctions?
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
What is the animal group with the most extinctions?
invertabates are the animals with the most extinctions
Where are most extinctions occurring today?
Tropical rain forest
What has changed most of the mass extinctions on earth?
climate change
Past mass extinctions most likely occurred as a result what?
Sudden changes in environmental conditions.
In what phase or state do most chemical elements occur naturally?
in solids i think
Which factor is most responsible for species extintion?
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.
Where does flooding most often occur?
well, i think that most flooding ocurrs in basments in peoples houses
Where most motorcycle crashes occur?
i think it is at an intersection. i have it on my traffic school online thing. hope it helped.. =]
What type of reactions is most likely to occur when barium reacts with fluorine?
I think it's a synthetic reaction
What is the group with the most extinctions?
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.
Which country is responsible for the most animal extinctions?
Africa during to the levels of environmental issues the eating,killing and really poaching yeah!!!
