human activity can affect ecosystems by removing producers, consumers and decomposers. What limiting factors may result from human actions, and what affects might they have on the flow of energy and matter in s ecosystem?​

Answers

A limiting factor is anything that constrains a population's size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource. For example, if there are not enough prey animals in a forest to feed a large population of predators, then food becomes a limiting factor. Likewise, if there is not enough space in a pond for a large number of fish, then space becomes a limiting factor.

Answers

More information is needed about the father's genotype before the version of the trait that would be displayed by the child can be predicted (option D).

What is genotype?

Genotype is the part (DNA sequence) of the genetic makeup of an organism which determines a specific characteristic (phenotype) of that organism.

The genotype responsible for a trait in an organism is usually in pairs or versions called alleles. The allele can either be dominant or recessive depending on whether it is expressed or masked respectively.

According to this question, a mother with the genotype "Aa" displays the dominant version of the trait. Her husband also displays the dominant version of the trait.

However, the exact genotype of the father is required to be able to predict the genotypic outcome of their offsprings.

What would happen to an ecosystem if an invasive
species has no predators? Explain in detail.

Please help!!!!!!!!!!

Answers

Explanation:

the top predator is removed from the delicate balance of any particular ecosystem, there may be disastrous effects for the other plants and animals that inhabit the environment.

When a top predator is removed from an ecosystem, a series knock-on effects are felt throughout all the levels in a food web, as each level is regulated by the one above it. This is known as a trophic cascade. The results of these trophic cascades can lead to an ecosystem being completely transformed. The impacts trickle down through each level, upsetting the ecological balance by altering numbers of different animal species, until the effects are finally felt by the vegetation

When a top predator is no longer present, populations of their herbivorous prey begin to boom. Without a top predator to regulate their numbers, these animals put a great deal of pressure on the existing vegetation that they require for food and can destroy large amounts of plant life, such as grasses and trees. This then causes further problems, such as soil erosion and loss of animal habitat. Eventually, humans are also impacted due to the resulting lack of soil fertility and clean water that depend on these plants.

Another problem involving the loss of vegetation is the competition that is created between herbivorous species. Competition between species for the remaining plant life is high and weaker species lose out to stronger ones, leading to the potential loss of weaker animals, as well as plant species. Increased competition, therefore, leads to a lack of biodiversity. In contrast, top predators often have varied diets, which means they can pursue a new food source if one is running low, preventing the first source from being eradicated completely. This is one of the ways that top predators are able to maintain biodiversity and the balance of an ecosystem.

The presence of a top predator also helps to maintain balance in an ecosystem by influencing the behaviour and movements of its prey through the fear of being caught. Animals that are prey to a top predator will move around in order to avoid it. This prevents plants and animals in any particular area of an ecosystem from being over-consumed, preserving food sources and habitats. In the absence of top predators, this regulation disappears, allowing certain areas of vegetation to be destroyed completely.

Answer:

That species would likely run rampid, due to it having no predators. The ecosystem may eventually recover, but it won´t be the same.

In the 1950s, Stanley Miller and Harold Urey designed experiments that tested Alexander Oparin's and J.B.S. Haldane's hypothesis that conditions on the primitive Earth favored chemical reactions that synthesized more complex organic compounds from simpler organic precursors. Miller and Urey used an apparatus that recreated the conditions of what a primitive Earth was thought to consist of at the time. Methane, hydrogen, ammonia, and steam were all included to recreate conditions similar to that of a primitive Earth. Their goal was to create complex organic molecules from the simple organic molecules that were believed to be part of primitive Earth's makeup. The Miller-Urey experiment was run for a week and the samples collected were analyzed. Analysis showed that some of the carbon in the apparatus was converted to amino acids molecules. In later experiments, similar to Miller and Urey's, it has been shown that it is possible to form all 20 amino acids commonly found in organisms. Along with nucleic acids, other molecules were detected in samples. Some of these were sugars, lipids, adenine, and even ATP in certain conditions.
