How have increased carbon dioxide levels and temperatures affected living organisms?
d1i1m1o1n [39]

Answer:  

Carbon dioxide is a gas which is released in the atmosphere as greenhouse gas, burning of fossil fuel, released in respiration process. Rise in the levels of carbon dioxide and other gases has resulted in increase in global temperatures. Increase in carbon dioxide and temperatures are responsible for weather fluctuations and global warming.

Weather fluctuation means untolerated heat and lack of precipitation or rain. Weather fluctuations will affect seasons. Seasons are necessary for maintaining the life cycle of organisms. Inappropriate seasons due to climatic change will affect the life of living organisms.

Global warming is an issue which is mainly due to release of hot heat trapping  gases from green house and other sources, increasing the atmospheric temperature. This will result in melting of ice from glaciers in world. The inhabiting animals living in the glaciers will suffer a lot from this as they cannot tolerate warm climatic conditions.

During upwelling, nutrient-rich water rises to the surface. How would this most likely affect the biotic components of the ecosy
hodyreva [135]

Answer: Increase in species numbers and diversity

Explanation:

Upwelling is an oceanographic phenomena in which the water from the bottom layers of the ocean usually above the seafloor get displaced and reach upto the surface layers with the effect of wind currents. The water carries away along with it the nutrients and the organic matter to the surface layers which allows the efficient growth of plant and planktonic diversity which favors the growth of sea animals like fishes and others. Hence, by this way the species diversity and numbers increases by the process of upwelling.

How do enzymes affect chemical reactions in living organisms
Arisa [49]

Answer:

Enzymes are catalysts for chemical reactions in living things. Enzymes, like other catalysts, lower the activation energy and increase the rate of chemical reac- tions. ... This means that enzymes do not change the direction of a reaction— they just change the amount of time needed for equilibrium to be reached.
