Answer:
Deforestation negatively impacts the <u>carbon cycle</u> as <u>trees</u> play an important role in <u>balancing the amount of carbon in the atmosphere</u>.
Explanation:
Deforestation is one of the most damaging activities to the environment due to different reasons but mainly because it releases important amounts of carbon dioxide to the atmosphere due to the logging and burning of forests and also leads to the reduction of fauna populations because of habitat destruction.
In this case, cutting white and red pines and then setting a pine acreage on fire disrupts the carbon cycle because:
a) [As stated above] <u>Trees play an important role in balancing the amount of carbon dioxide (CO2) in the atmosphere</u><u> as there is less photosynthesis carried out by plants - important part of the carbon cycle.</u>
b) <u>When </u><u>trees (wood) are burned, the carbon that was formerly stored is released into the atmosphere as CO2,</u> leading to another disruption in the carbon cycle.
Answer:
They have tissues, organs, and organ systems.
Explanation:
While all animals are multicellular, heterotrophic, eukaryotic and ingest their food, not all animals have tissues, organs, and organ system.
<em>The simplest group of animals, the sponges, are made up of several cells that have minimal interaction with one another. Hence, while sponges are multicellular, they are not at tissue level of body organization.</em>
All the options are true for all animals except the last option.
