competition

Answers

Answer:

competition

Explanation:

An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition and distribution are determined by environmental factors such as soil type, position in the landscape, altitude, climate and water availability(Department of Agriculture).

A climax community refers to the last stage of ecological succession in which the community remains relatively unchanged unless it is destroyed by events such as fire or human interference.

Competition between species in the same habitat is an important biotic factor in discussing ecological succession and the emergence of climax communities. Competition leads to a drop in the diversity of species in a given ecosystem because the dominant species live on and reproduce while the other species die off.

A scientist is examining layers of the
earth and tracking information about
animal fossils found in each layer. For
many of the deeper layers there are
consistently large animal skulls but
there is a sudden shift in the skull size in
one layer and they are all much smaller
at that point for the remaining layers
until the earth's surface. What does this
suggest?

Answers

This suggests that sudden change that occur to the environment cause a different size animal to become the main species of that area.

Why the fossils of small skull organisms were found?

This is because at that particular environment the small skull organisms can survive at that time as compared to big skull animals. The presence of a specific type of fossil in the soil layer shows that the fossil organism live at that time on this area due to the presence of good environmental conditions so we can conclude that environment was good for the small skull organisms at that time.

What are three ways a plant's organ systems work together?

B. The root system delivers materials from the soil to the shoot
system
The ground tissue of the root system protects the vascular tissue
in roots
D. The ground tissue of the root system stores food for later use by
leaves

Answers

Answer: A, B, D

Explanation: credit to the comments on the other. I also did the test

The three ways through which a plant's organ systems work together are as follows:

The shoot system delivers food to the root system.The root system delivers materials from the soil to the shoot system. The ground tissue of the root system stores food for later use by leaves.

Thus, the correct options are A, B, and D.

How do plants deliver water and nutrients to other parts?

Plants deliver water and other nutrients to other parts with the help of vascular tissues like xylem and phloem.

Xylem transports water, nutrients, and other minerals from the soil to all parts.

Phloem mediates the migration of foods from the leaves to the rest of the plants.

The shoot system delivers food to the root system via the vascular tissue phloem. The root system delivers materials from the soil to the shoot system via the vascular tissue Xylem.

The ground tissue of the vascular plant is responsible for storing the carbohydrates constructed by the plants and utilized by the leaves when required.

Therefore, the correct options are A, B, and D.

Earthworms are extremely beneficial in agriculture. They aid in the following ways:

They help loosen up and aerate the soil as they burrow deep. This aids in the respiration of the roots of the plants, making them penetrate deeper and grow well

They are being used presently in vermiculture to produce high-quality manure

They are also used as baits to catch fish

They keep interchanging the topsoil with the layer just below, thereby increasing soil fertility.

The excreta of earthworms is rich in the nitrogenous matter and is required for plant growth

B. Have long wavelengths.

C. Travel at high speeds.

D. Have short wavelengths.

Answers

Answer:

Its A

Explanation:

Its A =Have high amplitudes

Low-frequency waves have long wavelengths. Therefore, option B is correct.

What are waves?

Waves are a type of disturbance that travels through a medium or space, transferring energy without transferring matter. Waves can take many forms, including sound waves, light waves, water waves, and electromagnetic waves.

Waves are characterized by a number of properties, including wavelength, frequency, amplitude, and velocity. Wavelength is the distance between two consecutive peaks or troughs in a wave, while frequency is the number of wave cycles that occur per unit of time. Amplitude is the height of the wave, and velocity is the speed at which the wave travels through the medium.

Low-frequency waves have longer wavelengths, which means that they have fewer cycles per second (measured in hertz) and take more time to complete one full cycle. Therefore, option B is correct.
