Zarrin [17]3 years ago
4 0

Answer:

The correct answer will be option-D.

Explanation:

Darwin is best known for his theory of evolution which he proposes after collecting the specimens of plants and animals on his voyage.

He observed the similarity and differences of the morphological pattern as well as the species present in the area. On the basis of his conclusions, he suggested that organism get traits from their parents and species to change over time also called descent with modification.

One of the evidence that supported his concept is that he observed plant species in South America and found that these species closely resembled the species of the tropical regions of South America rather than species of the temperate region of Europe as the habitat was same.

Thus, option-D is the correct answer.

Question 9 (Multiple Choice Worth 2 points)
Vilka [71]

The two organisms that are most closely related according to Linnaean taxonomy are <em>Felis catus</em> and <em>Panthera pardalis</em>, because they belong to the same family

<h3>What is taxonomic classification?</h3>

Linnaean system of classification consists of a hierarchy of groupings called taxon. Each taxon is arranged in a hierarchical order.

The hierarchical arrangement of the taxon are as follows:

  1. Kingdom
  2. Phylum/Division
  3. Class
  4. Order
  5. Family
  6. Genus
  7. Species

These taxa are arranged from the most inclusive to the most exclusive i.e. members of the same species are the most closely related in that order.

This suggests that <em>Felis catus</em> and <em>Panthera pardalis</em> are the most closely related because they belong to the same family.

Why is the energy reduced at each level of the energy pyramid
Nostrana [21]

Answer: because every time something eats something 10% of the energy is passed on so it starts as 100% with plants photosynthesizing then the herbivore gets 10% of that energy. The carnivore that eats the herbivore gets 10% of the herbivore’s energy so by the time it gets to the top of the pyramid there is less and less energy to consume.
