the number of consumer can never exceed the number of producer in nature why​

Answers

Answer:

The number of consumer can never exceed the number of producer in nature because there is a limited amount of producer in the nature so the consumers is the one who eats a producer !

When the number of consumers increases, producers disappear due to overconsumption and consumers disappear due to lack of food and the ecosystem is destroyed. Therefore, in nature the number of consumers can never exceed the number of producers.

What are Producers and Consumers?

Producers are plants that make their own food, the energy they need to grow, reproduce, and survive. They are making their own food which makes them special. These are the only living things on Earth that can make their own source of food energy with the help of sunlight, water and air.

Consumers make up the upper trophic level. Unlike producers, they cannot make their own food. They obtain their food by eating plants or other animals, while some eat both.

Scientists distinguish between several types of consumers. Primary consumers form the second trophic level.

Thus, when the number of consumers increases, producers disappear due to overconsumption and consumers disappear due to lack of food and the ecosystem is destroyed. Therefore, in nature the number of consumers can never exceed the number of producers.

A sample of Carbon-14 originally contained 100 g. After three half-lives have
passed, how much Carbon-14 is left?

Answers

Answer:

After 3 half lives 12.5 g of C-14 left

Explanation:

Given data:

Mass of C-14 = 100 g

After 3 half lives mass left = ?

Solution:

At time zero = 100 g

At first half life = 100 g/2 = 50 g

At second half life = 50 g/ 2 = 25 g

At third half life = 25 g/2 = 12.5 g

Thus, after 3 half lives 12.5 g of C-14 left.

Describe the process of photosynthesis,include what is needed and what is produced.Provide an explanation as to why photosynthesis is needed for plants to maintain homeostasis.

Answers

Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants. After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

Answer:

What are some of the ways that parasites have adapted to transmission between hosts and resisting the host’s attempts to get rid of the parasite? How do these particular developments help the parasite?

Answers

Answer for you
Organisms depend on other species for resources such as nutrients. Parasites live in or on another organism, which is called the host. The parasite takes what it needs from the host but the host receives nothing in return and often suffers as a result. An example of parasitism is the relationship between fleas and dogs. Fleas live on dogs and feed on their blood. The dog receives no benefit but the fleas are provided with food and a habitat. Fleas attach themselves to hairs and can spread from one host to another by jumping huge distances.

A tall, green plant with dominant alleles for both characteristics  have a genotype TTGG and its phenotype is tall and green.

Explanation:

For a given trait, the dominant allele of the allelic pair is represented in capital letters (T and G), while the recessive allele is represented in small letters (t and g).

In the case of this plant, whose phenotype is tall and green —both dominant characteristics— and considered pure because both alleles are dominant, the genotype is TTGG.

In the case of a hybrid, the phenotype would be the same but the genotype would be TtGg. A recessive phenotype would be ttgg.

how does increasing the size of the habitat affect carrying? explain your answer. recall the scenarios: 0-15 years, little land; 15-30 tears, moderate land;30-45 years, ample land

plzzz helpp ​
I meant years not tears

Answers

Answer:

so basically carrying capacity is "the amount of organisms a specific environment can support", so if the environment is increased, most likely, more space and food will be available, which means the environment can hold more organisms, causing the carrying capacity to increase

Explanation:

what I just said lol

Answer:

Increasing the habitat size will increase the carrying capacity. Carrying capacity is the maximum amount of organisms a habitat and its resources can carry. So if the habitat expands and more resources become available, the population would expand. As you can see for the first 15 years, when it was the little land, there was only about () rabbits, but as the land grew throughout the years, the rabbit population grew. 15-30 years with moderate land had around () rabbits, and the ample land in years 30-45 had around () rabbits, a little over two times the amount the little land had.

2. How are the kelp and the chemosynthetic bacteria of the
hydrothermal vents similar?
A. Both use energy from the sun to make food.
B. Both are primary producers.
C. Both are scavengers.
D. Both use hydrogen sulfide as an energy source.

Answers

Answer:

C. Both are primary producers.(THIS IS THE CORRECT ANSWER)

Explanation:

Chemosynthesis is a biological conversion of carbon molecules. These are found around the hydrothermal vents.

It is due to the bacteria feeds on the hydrogen sulfide that is coming out from the vents that are required as an energy tonic for the bacteria to survive and kelp also has similar requirements. Kelps forests are shelters for these bacteria and hence both are found near the source of energy.  

Hence the option B both are primary producers.

Explanation:

During an experiment to determine if people with more symmetrical body features have a lower incidence of disease, a researcher first measures the length of several bones in the subject's hands and arms. The device used to measure length does not display a readout of the measurement taken. Instead, a wire connects the measuring device to a computer that records the data. The computer monitor is kept out of sight of the subject and the researcher. Why is such an elaborate device used?a. So that the subject will not know if he or she is part of the control group.b. So that the experiment will be repeatable.c. So that the subject will not be injured by the experiment.d. So that the identity of the subject will remain anonymous.e. So that the measurements are not biased by the researcher.

Answers

Answer:

e

Explanation:

The main reason such an elaborate device was used would be to eliminate any element of bias by the researcher.

It is important to eliminate biases when taking measurements so as to ensure the accuracy of the data and the overall outcome of the experiment. If a simpler device had been used in which the researcher manually records the length of the bones, it is possible to knowingly or unknowingly introduce biases or random error into the experiment which will impact the integrity of the data and the outcome of the experiment.

The correct option is e.

The characteristics that protists and fungi both have that make them eukaryotes is the possession of a membrane bound nucleus and other organelles.

EUKARYOTES:

Eukaryotic cells are cells that possess a membrane-bound nucleus to house their genetic material (DNA). Eukaryotes also possess other membrane bound organelles like mitochondria, golgi apparatus etc.

This feature particularly differentiates them from prokaryotic cells. Eukaryotic organisms include plants, animals, fungi, some protists etc.

Therefore, it can be said that the possession of a membrane bound nucleus and other organelles is the characteristics that makes fungi and protists be considered eukaryotes.
