Does the process of evolution occur at the individual level, where selection happens to individuals, or at the population level, where selection happens to populations?
Evolution occurs at the population level, where selection happens to populations rather than individuals.
What do scientists think happens is population change over time?
Scientists believe that populations can fluctuate in size over time due to factors such as birth rates, death rates, immigration, and emigration. These changes can be influenced by various factors like available resources, competition, predation, disease, and environmental conditions. Over time, populations may reach a stable size (carrying capacity) or experience boom-and-bust cycles depending on these factors.
What factors support evolution-?
As we currently understand it, evolution happens if: - There are populations of organisms reproducing with variation - Those variations are inherited by offspring - More offspring is produced than can comfortably subsist in the habitat - Offspring therefore compete with one another for resources and mating opportunities - Variant inherited traits affect their ability to compete.
How long does the process of natural selection and evolution take?
The process of natural selection and evolution can vary in terms of the time it takes, ranging from hundreds to millions of years depending on the species and environmental factors. Evolution is a gradual process that occurs over generations as populations adapt to their changing surroundings through natural selection.
What is the difference between population community ecosystem and biosphere?
A population consists of individuals of the same species living in the same area, a community is a group of different populations living together in the same area, an ecosystem includes both living (biotic) and non-living (abiotic) components interacting in a specific area, and a biosphere encompasses all the ecosystems on Earth.
What happens to the diversity after fragmentation?
Fragmentation can lead to a decrease in genetic diversity within populations and increase isolation between populations which can then decrease overall species diversity in an area. This can result in reduced resilience to environmental changes and increase the risk of local extinctions.
Is nitrogen biotic factor or abiotic factor?
no, it is not a biotic factor it is a cycle which combines different elements together and converts molecules to other ones. it is not biotic nor is it abiotic but rather it includes both biotc and abiotic factors such as soil, lightning, producers, consumers, decomposers, etc
What are some kinds of nonliving things in the tundra?
there is a part of a ground called permafrost which happens when the ground freezes. There also grasses lichens and mosses. rocks,air,water and soil are the abiotic factors.
What happens when an ecosystem is in equilibrium?
When an ecosystem is in equilibrium, it means that the various biotic (living) and abiotic (non-living) components are in a stable balance, allowing populations of species to thrive without significant fluctuations. Resources such as food, water, and habitat are available in sufficient quantities, enabling organisms to coexist and maintain their populations. This stability supports biodiversity, as species interactions like predation, competition, and symbiosis are finely tuned. However, even in equilibrium, ecosystems can be influenced by external factors, which may lead to shifts in balance over time.
Does the process of evolution occur at the individual level, where selection happens to individuals, or at the population level, where selection happens to populations?
Evolution occurs at the population level, where selection happens to populations rather than individuals.
Is coral bleaching abiotic or biotic?
um no algae is biotic because it is a plant um no algae is biotic because it is a plant
What happens to the strength of a base as the pH value increase?
Also increase.
What happens when two populations have been reproductively isolated and can no longer breed?
Speciation
What happens to populations when water supplies become contaminated?
Everyone will become sick.

What are some abiotic factors in a Bamboo Forest?
Some abiotic factors in a Bamboo Forest include sunlight, temperature, rainfall, humidity, and soil composition. These factors play a crucial role in determining the growth and distribution of bamboo plants within the forest ecosystem.
