<span>a)
</span>The milkweed is the primary producer in the
ecosystem. It manufactures food from the abiotic factors in the soil such as
nitrates and water and those in the atmosphere such as carbon-dioxide and
sunlight. The milk weed is then fed on by the caterpillar and a primary
consumer. The caterpillar is then fed on the mocking bird (secondary consumer)
<span>b)
</span>Increased human population growth and their activities
have resulted in the emission of carbon dioxide and other greenhouse gases in
the atmosphere. This has increased the global temperature. This increase of
global temperature increase ocean temperatures causing coral bleaching.
Another example is depletion of water sources
by human activities hence causing drought. Drought reduces the amount of
vegetation growth due to scarcity of water in the soil (due to lowering of the
water table) for plant growth.
Answer:
Memory and learning - Cerebrum
General bodily arousal - Cerebellum
Complex mental processes - Cerebral cortex
Connects two halves of brain - Cerebrum
Relax, dream, sleep - Hypothalamus
maintain homeostasis - pons
Regulates body circulation - Medulla
Emotions - Cerebrum
Tells senses - Cerebrum
tells nervous system - Cerebellum
Explanation:
Cerebrum is the largest part of the brain which controls emotion and senses of the body. It controls information of the body. Medulla Oblongata is the part of the brain which is just near the spinal cord. It regulates blood circulation. Hypothalamus is the part of brain which regulates sleep wake cycle of a person.
what do this mean do you want free points
D, because if you burn fossil fuel the smoke while burning the fossil fuel is carbon dioxide and we live off fossil fuel and that means we use a lot of fossil fuel.
