Describe the flow of energy to the lion using a food chain from the food web that includes a rabbit.​

Answers

Answer:

10%

Explanation:

the sun gives energy to the grass (to make it easier to understand, say the sun gives 100un of energy to the plants)

from there, the rabbit eats the grass( 10% of 100 is 10, so the rabbit gets 10un of energy)

and the, a lion eats the rabbit (10% of 10 is 1, so the lion gets 1 un of energy)

every single time a predator consumes prey, it only gets 10% of what the prey gets from its prey.

What is reflex arc?

A reflex arc is a neural pathway that mediates a reflex action. It is a rapid and automatic response to a specific stimulus that does not require conscious thought or decision-making from the brain. When a sensory receptor in the body, such as the skin or muscles, is stimulated, a nerve impulse is transmitted to the spinal cord, where it is processed by an interneuron.

The interneuron then sends a signal through a motor neuron to the effector, such as a muscle, causing a rapid and involuntary response, such as pulling your hand away from a hot stove. This entire process occurs without conscious control from the brain, allowing for quick and protective responses to potentially harmful stimuli.

Explain the role of both biotic and abiotic factors within a nutrient cycle.

Answers

Answer:

Answer. Biotic factors are the living things in an ecosystem so they do not recycle. Abiotic factors are the different physical and chemical components available like temperature, air, water, minerals, rocks,and PH. Not ll of them are recycled.

The role of both factors within a nutrient cycle is very important  because nutrients cycling through biotic and abiotic systems constantly.

Explain the role of both biotic and abiotic factors within a nutrient cycle?

Plants, animals, microorganism and organic matter are the biotic locations of nutrients while on the other hand, the atmosphere, water, and soil represent the abiotic locations. Nutrients are constantly moving or cycling through biotic and abiotic systems.

So we can conclude that the role of both factors within a nutrient cycle is very important  because nutrients cycling through biotic and abiotic systems constantly.

what ways do we use patterns of classification in science? give examples

Answers

Answer:

Classification is the way scientists use to categorize and organize all of life. It can help to distinguish how similar or different living organisms are to each other

Explanation:

Patterns are used in science to classify objects or phenomena into groups. There are patterns of both similarity and difference.

What is classification?

Classification is the way scientists use to group and categorize objects, phenomenon or life forms. It can help to distinguish how similar or different living organisms are to each other based upon the pattern of their structure and organization.

Patterns are regular and intelligible forms , sequences, or structure that  found throughout nature. Scientific questions may be generated when scientists observe a pattern of events or when something does not match an established pattern.

For example, the frozen water in an iceberg is arranged into a regular, repeating crystal structure—a pattern of similarity. Young children can observe a common pattern of difference, the differences between adult animals and their offspring.

Thus, it is clear from above explanation,  the ways to use patterns of classification in science.
