Trees and shrubs, giraffes (who eat trees and shrubs), and lions are all connected by a straightforward food chain (that eat the giraffes). Every link in this chain provides fuel for the one after it.

Energy from the sun is the source of all food chains. Plants capture this energy. There are at least two or three trophic levels in every food chain and web. There are often no more than four trophic levels. Many consumers consume food at various trophic levels. When people eat plants like vegetables, they are the main consumers.

Who eats whom is described in a food chain. All of the food chains in an ecosystem make into a food web. Each organism in an ecosystem resides at a certain trophic level, position, or web of relationships with other organisms. The base of the trophic pyramid represents producers—animals that synthesise their own food through photosynthesis or chemosynthesis.

Answer:

The correct answer is: wildflowers, rabbits, foxes

Explanation:

The correct answer is: wildflowers, rabbits, foxes

In a food chain, energy is transferred from one organism to another in a linear sequence. The organisms at the beginning of the food chain are usually producers, such as plants, which are eaten by herbivores, such as rabbits. In turn, the herbivores are consumed by predators, such as foxes.

In a temperate deciduous forest, wildflowers are a common type of plant that can be eaten by rabbits, which are in turn eaten by foxes. Therefore, the correct food chain is wildflowers (producer) → rabbits (herbivore) → foxes (predator).

Answer:

The tenet of cell theory that BEST serves as a basis for this type of biotechnology is that all living things are composed of cells.

Cell theory states that all living things are composed of one or more cells and that the cell is the basic unit of life. In biotechnology, genes that code for a specific protein can be inserted into bacterial plasmids, which are small circular pieces of DNA found in bacteria, and then the plasmids are used to transform cells. The transformed cells can then produce the desired protein. This process is based on the understanding that all living things are composed of cells and that the genetic information necessary to produce specific proteins is contained within the cell's DNA. Without this understanding of the basic unit of life being the cell, it would not be possible to create transgenic bacteria to synthesize human proteins for medical use.

Option D is Maintaining genetic diversity within a crop type is important because High genetic variety in crop fields allows for more efficient harvesting by farmers

Agriculture dramatically reduces the genetic diversity of plants on earth in a world of genetically modified (GM) crops, and by ignoring genetic diversity, the possibility of the extinction of many native or indigenous crops that are currently grown is evident.

The purpose of genetically modified plants is to develop a superior variety and increase nutrients in a certain food, but the end product is not a healthy choice for people because the GM plants are not friendly to the gut bacteria and have many other negative effects.

So, by neglecting genetic variety, the likelihood that many native or indigenous crops included in Option D will go extinct is increased.

can u understand this

A sea breeze describes a wind that blows from the ocean inland towards land. This breeze occurs most often in the spring and summer months because of the greater temperature differences between the ocean and nearby land, particularly in the afternoon when the land is at maximum heating from the sun.

During the day, the sun heats up both the ocean surface and the land. Water is a good absorber of the energy from the sun. The land absorbs much of the sun’s energy as well.  However, water heats up much more slowly than land and so the air above the land will be warmer compared to the air over the ocean. The warm air over the land will rise throughout the day, causing low pressure at the surface. Over the water, high surface pressure will form because of the colder air. To compensate, the air will sink over the ocean. The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean.

Answer:

A non-example of brackish water would be water that is not a mixture of fresh and saltwater. For example, distilled water, which contains no dissolved salts or minerals, would be a non-example of brackish water.

From the rock record and fossil record, scientists can infer the history of the Earth and the changes that have occurred over time. The rock record provides information about the physical and chemical properties of rocks and their formation, while the fossil record provides evidence of the past life on Earth.

One specific example of evidence from the rock record is the principle of superposition. This principle states that in a sequence of undisturbed rocks, the oldest rocks are at the bottom and the youngest rocks are at the top. By studying the order of rock layers, scientists can determine the relative ages of the rocks and the events that occurred during their formation.

Another example of evidence from the fossil record is the concept of index fossils. Index fossils are fossils of organisms that lived during a relatively short period of geologic time and were widespread, making them useful for dating rocks and correlating geologic events. For example, the trilobite species Phacops rana is an index fossil of the Ordovician period, which helps scientists to identify and date rocks of that age.

Overall, the evidence from the rock and fossil record helps scientists to organize geologic time by providing a relative timeline of events and the evolution of life on Earth.
