What is the source of energy for whom?

The plants use the sun as their energy, using photosynthesis.
The insect and animals get their energy from the food they eat.
And bacteria get their energy by decomposing dead organisms.

You might have to do the research on what each animal eats if you need specific answers.
I'm sorry this isn't much, but hope this helps you out! :)

Answer:

Resistance bacteria survive in greater numbers and pass the trait to their offspring

Explanation:

Antibiotics are chemicals which are used in the treatment of bacterial infections. The bacteria sometimes have some form of immunity or resistance to a particular antibiotic due to a host of underlying factors.

Once resistance appears in a bacterial population, it spreads rapidly. The trait of immunity or resistance to such antibiotic is then passed as a trait from one generation to another.

How does biogeography provide evidence for evolution.

Liula [17]

The global distribution of organisms and the unique features of island species reflect the evolution and geological change. Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.

Natalka [10]

Explanation:

From the diagram with corresponding labels:

Exocytosis
Facilitated diffusion
Endocytosis
Diffusion
Active transport

Further explanation:

Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

Via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid by layer this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

Active transport is a mediated process that requires the use of specialized membrane proteins these proteins require energy in the form of avenues and triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules.

Carrier proteins and channel proteins are the two major classes of membrane transport proteins; these allow large molecules called solutes (including essential biomolecules) to cross the membrane. Channel proteins which are pores filled with water versus enabling charged molecules to diffuse across the membrane, from regions of high concentration to regions of lower concentration. This is a passive part of facilitated diffusion

...some very large molecules require specialized type of active transport in order to move across the membrane this includes endocytosis and exocytosis

During endocytosis large molecules cells and cell fragments moved across the plasma membrane through a process of invagination; piece of the external cell membrane falls into itself and forms a small pocket that surrounds the target molecule this breaks off from the membrane to form an intracellular vesicle; different methods of endocytosis such as Phagocytosis, Pinocytosis and receptor-mediated endocytosis, take in cells, water and targeted substances respectively.

Similarly, in exocytosis, the particles (Protein, Waste material etc.) surrounded by a phospholipid membrane. However, this membrane is formed in the cytoplasm, and attaches to the plasma membrane’s interior in a process opposite to endocytosis; material is removed from the cell and exported into the cell’s exterior called the extracellular space.

A book review would be considered

masha68 [24]

It is definitely not a primary source: this would be a book itself.

Now, is it a tertiary source? I don't think so: the author of the review should have read the book and should only be referring to this book in the review.

I think it's a secondary source.
