Starting from the sun, create a food chain including at least three organisms. Explain how energy is transferred through the cha

Kryger [21]

Answer:

The food chain showing seven organisms can be drawn as follows:

Plants → grasshoppers → mice → frog → snakes→ eagles → decomposers

The plants are the primary source of food in a food chain or a food web. The animals which feed on plants will be termed as herbivores or primary consumers like the grasshopper. The organisms feeding on primary consumers will be the secondary consumers like mice.

An energy pyramid for three of the organisms can be shown as follows:

mice (10 kilocalories)

↑

Grasshoppers (100 kilocalories)

↑

Plants ( 1000 kilocalories)

As the energy pyramid shows, only about 10% of the energy travels from one trophic level to another.

You are looking at tissue under a microscope. One cell shows half the amount of DNA of some of the other cells. This cell is most likely to be in the G1 phase where the cell has just divided.

Ivanshal [37]

Answer:

Diffusion

Misha Larkins [42]

Answer:

The theory of evolution first formulated in Darwin's book is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits that allow them to better adapt to its environment, survive and have more offspring.

Ernst Mayr divided Darwin's theory into 5 unique parts.

Ernst Mayr divided Darwin's theory into 5 unique parts.Evolution as such

Along with Buffon and Lamarck, Darwin supported the ability of species to change over time.

Common Descent

Darwin felt that all of the diversity of life on earth emerged out of the evolution from one or a few common ancestors.

Gradualism

While Lamarck felt that species-wide change could take place within the span of a few generations, Darwin felt evolution was a much slower process, taking place in innumerable small steps.

Population Speciation

This portion of Darwin's theory states that within a population, change in a species occurs as the balance of hereditary characteristics shifts across that population. This differs from Lamarck's idea that each individual in the population must undergo the same change. According to Lamarck, all giraffes living under tall trees would develop long necks. According to Darwin, some would randomly be born with long necks, this hereditary trait would gradually spread throughout the population.

Natural selection

Natural selection is often called the most unique part of Darwin's theory. Competition had been thought of as a reason that a given species might succeed or go extinct, but Darwin extended the understanding to change within a species. To continue the example of giraffes: when a giraffe is born with a longer neck than its fellows, it gains an advantage because it is able to reach more food. The long-neck giraffe is therefore stronger, lives longer, and more likely to have offspring. These offspring are born with the same long neck as their parent, though some might have even longer necks.

Returning to the example in the figure, in the first generation the application of the pesticide causes the death of most of the non-resistant insects: only those resistant to the pesticide survive. These insects reproduce and maintain their resistence so that the second generation will be more resistant than the first. So we have Natural selection, speciation, gradualism and evolution in act all together.

Drag each tile to the correct location.

OLEGan [10]

Answer:

Plant-like:

presence of flagella

shows the absence of cell wall, though chloroplast may be present

Animal-like:

absence of cell wall, as well as chloroplast

Fungus-like:

feeds on decaying matter

enclosed by a membrane called a pellicle

slime mold belongs in this category

Explanation:

The protists can be classified into three groups (plant-like, animal-like, fungus-like) based on the method of nutrition, movement, and mode of reproduction.

Plant-like protists have chloroplasts and trapped sunlight to form food ad energy (photosynthesis). They also have flagella used for the movement.

Example: Algae

Animal-like protists are heterotrophs that cannot make their food. They do not have chloroplast and cell wall outside the cell membrane.

Example: Protozoa

Fungus-like protists are single-cell eukaryotes that have a protective layer outside the cell membrane called pellicle. They feed on decaying organic matter.

Example: Slime mold and water mold
