What type of evolution is a slow change of one species to another?
Isolation of population and impact of climate change creates speciation. It is the method of slow change of one species to another.
What species has the greatest impact on the biosphere?
humans :)
What term is defined as a species that has a big impact on a community relative to its abundance?
keystone species
What is keystone species?
Keystone species are those which play a major role in determining which species exist in a particularcommunity. They are critical factors in ecological processes such as energy flow and nutrient cycling.If we can identify a keystone species and quantify its impact on its community then we can usually understand how the community functions as a whole. The importance of these species is such that their loss from a community may bring about a cascade of other species extinctions. Often a keystone species is not recognised until it is wiped out and many other species which were dependant upon it disappear also.
How microevolution and migration can affect an ecosystem?
Migration can negatively impact an ecosystem if the migration is permanent and leads to the loss of native species. Temporary migration, such as in the case of birds flying south in the winter, can maintain the biodiversity of an ecosystem. Microevolution, like migration, can aid the survival of native species.
How do you make this sentence shorter nonnative species could often cause ecosystem wide impact?
Imported species may damage the ecosystem.
Could the sea lamprey have a major impact on the trout population in the Great Lakes?
Absolutely. As an invasive species, the lamprey has no natural enemies, and the fish of the Great Lakes have no defenses against them.
What is difference between competition and predation?
Competition: Introduced invasive species compete against native species for essential resources such as food and habitat.Predation: Introduced predators can have more impact on prey population than native predators, as prey may not have adaptions to escape or fight them.

How do invasive species disrupt ecosystems?
Invasive species have such an impact on the environment because they basically have no naturally known enimies. If they come from a different land, the organisms that are already living there aren't used to the envasive species being there, and have no natural defense against them. The invasive species will devour all it wants, and can wipe out an entire population of a species in an area.
Why are invasive species dangerous?
They can affect the chemical makeup of the water, availability of resources, and even alter the food web. Invasive species impact other species more directly through competition for resources. Because invasive species evolved with other competitors and native species evolved in the absence of invasive species they lack the ability to compete with invasive species. They are costly to society in many ways through both, direct management, and decreased production. The annual estimated cost in the United States of invasive species control is about 120 billion dollars per year. It is estimated that the global cost of invasive species management is equal to five percent of the global economy.
What change in the speciesĀ Homo sapiensĀ has had the biggest impact on the biosphere?
population growth
What change in the species homo sapiens has had the biggest impact on he biosphere?
population growth A+
Why invasive species dangerous?
Because they have a large impact on the ecosystems they invade. They can affect the chemical makeup of the water, availability of resources, and even alter the food web.
National ballast water laws in the US would hurt economic globalization?
"As the United States becomes more aware of its economic dependence on a global market and the impact that invasive species have in the movement of people, products, and supplies, so too will the role of the nation's socio-economic well-being become a part of the equation in managing invasive species." This is from the invasivespecies@doi.gov
What is anthropomorphic ecologies?
Anthropomorphic ecologies deal with the impact of human civilization on the environment. This kind of study looks into pollution, population, and impact on other species in proximity to humans.
What type of evolution is a slow change of one species to another?
Isolation of population and impact of climate change creates speciation. It is the method of slow change of one species to another.
