Answer:
Coral reefs are under threat if atmospheric carbon dioxide levels continue to rise, new research has shown. When CO2 dissolves in the ocean, it raises the water's acidity level. This prevents a build up of calcium carbonate, which corals draw from seawater to build their skeleton
Explanation:
<span>The amount of energy at each trophic level decreases as itmoves through an ecosystem. ... An energy pyramid is a model that shows the flow of energy from one trophic, or feeding, levelto the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level.</span>
Answer:
The correct answer is C. The tertiary structure of a polypeptide is the overall three-dimensional shape of a fully folded polypeptide.
Explanation:
A polypeptide is a molecular chain composed of at least 10 amino acids (which are the molecules that make up proteins). When we talk about its tertiary structure, it refers to the complete overall three-dimensional structure of the polypeptide units of a given protein, where the polypeptide chain is fully folded and compacted. This folding is facilitated by unions called disulfide bonds, which are created from the cysteine residues, these bonds (called disulfide bridges as well) help to stabilize many polypeptides.
Fundamental niche is the job/role that one species can have in the environment .
The realized niche is the role of a species influenced by several factors in the environment.
Example:
The fundamental niche of Yellow Warblers is found in a spruce tree.
The realized niche of the Yellow warblers is when they are "forced" to share the spruce tree and remain in one particular area of the tree while other warbler species play defense different niches in other parts of the tree.
:v it is like :
•Fundamental niche: [yellow warbler] "I got my home, all for me..."
~new species arrive to the spruce tree~
•Realized niche: [yellow warbler] oh, shoot! I gotta stay in the upper part/move to the upper part as the others warbler "struggle" to get territory :v or they just choose their own . :v
The Calvin cycle of photosynthesis starts when the energy of light is processed to chemical energy within the cells of plants. The ATP molecules created power the Calvin cycle. The Calvin cycle utilizes energy to create carbohydrates from h20 and co2.
