</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: True.
Spleen framework is created by reticular fibres from reticular cells.
Explanation:
Spleen is an organ found mostly in vertebrates. It develop from mesenchymal cells within the dorsal of mesogastrium near the greater curvature stomach. The mesencymal cells then divide and differentied to form framework of connective tissues of spleen. The framework of spleen is created by reticular fibres of the reticular cells. Reticular fibres are fibres in the connective tissue that is composed of type iii collagen secreted by reticular cells. Spleen function in filtering of blood. It plays a major role in red blood cells and immune system.
Properly identifying each species.
Accurately recording his findings.
