Which best describes darwin’s studies that led to the theory of evolution? extensive research of an individual organism within a short period extensive research of an individual organism over many years observations and data collected within a short period observations and data collected over many years

the correct answer at least on engenuity is d, observation and data collected over many years. i just took the test

Observations and data collected over many years

Explanation:

Darwin was the first scientist to offer scientific evidence on the evolution of species, through natural selection. However, he did not make this discovery overnight, or for a few hours. In order for Darwin to establish the theory of evolution, it was necessary for him to take a trip across five continents, observing the most varied number of species. In addition, he only created the theory after doing several experiments over a long 20 years.

For this reason, we can say that what best describes Darwin's studies that led to the theory of evolution are observations and data collected over many years.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
