Answer:
D
. Energy flows from the Sun or from rocks through the primary producers and the successive levels of consumers.
Explanation:
Energy flows only through the sun not the rock because sun is the ultimate source of energy which can be used by the plants for making their own food in the form of glucose during the process of photosynthesis. This plant is then eaten by primary consumer known as herbivore. These primary consumer is eaten by secondary consumer is called carnivores. The tertiary consumer feeds on the secondary consumer and so on. In the end, decomposers feed on the dead bodies of animals and releases nutrients which can be used again by the plants for making food.

sugar

The sides of the stepping stool are made of rotating sugar and phosphate particles. The sugar is deoxyribose. The rungs of the stepping stool are sets of 4 sorts of nitrogen bases. Two of the bases are purines-adenine and guanine.
<h3><u>Answer;</u></h3>
Divergent evolution;
<h3><u>Explanation;</u></h3>
- Divergent evolution is the process of two or more related species becoming more and more dissimilar. In this type of evolution groups of species from the same common ancestor evolve and accumulate differences, resulting in the formation of new species.
- For example; <em><u>The red fox and the kit fox. The red fox and the kit fox both have a common ancestor but have gone through the process of divergent evolution. It has adapted to its mixed farmland and forest environment. Its red color helps it to blend in with the trees. </u></em>
- <em><u>The kit fox is sandy in appearance because it lives in the desert. It also has larger ears than the red fox and its larger ears help the fox release excess body heat in the desert.</u></em>

Answer: Magnolia is a large genus of about 210 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. Magnolia is an ancient genus. Appearing before bees did, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels of Magnolia flowers are extremely tough. Fossilized specimens of M. acuminata have been found dating to 20 million years ago, and of plants identifiably belonging to the Magnoliaceae date to 95 million years ago. Another aspect of Magnolia considered to represent an ancestral state is that the flower bud is enclosed in a bract rather than in sepals; the perianth parts are undifferentiated and called tepals rather than distinct sepals and petals. Magnolia shares the tepal characteristic with several other flowering plants near the base of the flowering plant lineage such as Amborella and Nymphaea.
