what is the most abundant organism in a food chain​

Answers

The given question is incomplete as there is no food chain given in the question, but based on the knowledge it can be said so that producers are present in abundant amount in every food chain.

Answer: Producers

Explanation:

The producers can be defined as the organism which have the ability to make food. This food is used by the other organism of the food chain as a soul source of energy.

They are huge in number so that they can produce enough food to meet the requirement of other organisms. Though all of the organisms are not directly dependent on producers ,some of them(carnivores) are also dependent on the organism eating plants(herbivores).

Producers→ primary consumers(herbivores)→ secondary consumers(carnivores)→tertiary consumers(carnivores).

Here, we can see that the all the organism are directly or indirectly dependent on the producers and they are abundant in every food chain.

what evidence proves endosymbiosis happened

Answers

Answer:

Explanation:

The first piece of evidence that needed to be found to support the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and if this DNA is similar to bacterial DNA. This was later proven to be true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.

Ramer wants to find out how pressure affects the force of gravity acting on dust particles in a cloud. Ramer designs an experiment in which he places dust particles in a pressure chamber. He is able to adjust the pressure in the chamber from 0 Pascals to 780 Pascals. What should Ramer use as his control group?

Answers

Answer:

A vaccum should be used for the control group chamber.

Explanation:

In an experiment, a control is an experiment or observation designed to minimize the effects of variables other than the independent variable. The introduction of a control increases the reliability of the results; often through a comparison between the control measurements and the other measurements.

A vaccum according to this experiment is a chamber that will have no pressure within it. This will give a benchmark of the effect of pressure in this experiment.

a cell with a diploid number of 24 undergoes meiosis, how many chromosomes are in each daughter cell?

Answers

Answer:

it will have 12

you are welcome :)

When a cell with a diploid number of 24 undergoes meiosis, each daughter cell will have 12 chromosomes.

What is meiosis?

Meiosis is a process of cell division that generates haploid cells having half the number of chromosomes as the cell. It plays a role in reproduction by enabling the merging of two haploid cells to form a diploid cell with the complete set of chromosomes.

In this scenario the parent cell contains 24 chromosomes resulting in each daughter cell possessing 12 chromosomes.

Why Do You Think Soil Erosion Increased Over Time ?

Answers

Because Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. Activities that remove vegetation, disturb the ground, or allow the ground to dry are activities that increase erosion.

A population of pigs live on an island together with burrowing termites. Pigs that have the longest snouts tend to survive more frequently than those with shorter snouts. Over time, most of the pig population is made up of individuals that have very long snouts. This an example of which type of variation?

Answers

This is an example of natural selection. Because the pigs with the stronger snout survived more frequently, the other weaker ones died out. As a result, the stronger shouted pigs were the largest part of the population.

What small changes could we make in our everyday routines that could greatly impact our future and the future of species and biomes?

Answers

Answer:

Explanation:

Learning to take care of our environment is one great change that we need to make. Our environment is everything around us if we accept the task of taking care of it many species will be preserved for long. If I have river around me and I avoid polluting it to prevent accumulation of toxins in the water bodies this will help the biomes.

When trees are preserved and not been cut down indiscriminately reducing global warming in the environment this will also help preserve biomes.

Answer and Explanation:

There are many small changes that we can make in our everyday routines, and that will have a positive impact on future generations as well as on species and ecosystems.  

To name a few,

Transport: we can avoid using cars or motorbikes that need fuels, and we can try to move by bike or walking to other places that are not too far away from where we are. Fuel pollution is very harmful to the atmosphere because of the gasses production. Recycling: whenever it is possible we might try to transform things we do not use anymore in other things. In this way, we will avoid throwing objects that we can reuse.Composting: Every organic waste can be thrown in a pod or space with soil. Organisms will degrade this organic matter and will produce fertile soil.

Microplastics are currently in our ocean's food web.

True
False

Answers

Answer:

True.

Explanation:

However, it has been established that microplastics enter the food chain when animals eat or ingest contaminated food materials. ... Zooplankton, the microscopic sea organisms at the bottom of the food chain, is eaten by all kinds of fish. Fish ingest small pieces of plastic due to their continuous uptake of water.

Answer:

True

Microplastics are one of the most pervasive global pollutants, and their presence in our oceans is a cause for great concern. As the name says, these are micro particles, less than 5mm in size, that have either been deliberately manufactured (e.g., microbeads in cosmetics), or emerge as larger plastics break down (nets, bottles, bags, clothing, etc.). They are roughly the same size range as plankton, and so when they show up in marine ecosystems they have the potential to be consumed by a vast array of organisms.
