Answer:
In the freshwater food web,
the relationship between the minnow and the water fleas can be described as <u><em> Predator-prey relationship</em></u>
Explanation:
A food web can be described as a diagram which shows multiple food chains. It represents the 'predator-prey' relationship in an ecosystem.
The freshwater food web will described all the predator-prey relationships in the fresh water.
The minnows in the fresh water feed on larval fishes, mosquito larvae and water fleas. Hence, minnows will be the predators and water fleas will be the preys. So, these organisms will show a predator-prey relationship.
Answer:
Show that life can only come from life (rather than spontaneous generation)
Explanation:
Pasteur boiled a broth in a flask with an S-shaped neck. Thebend in the neck prevented particles from the air reaching the broth, but still allowed air to get in. No bacteria grew in the flask.
When the flask neck was broken so that particles could get inside, the broth became cloudy, showing that microorganisms were only able to grow from other living things from the outside, and not spontaneously from nothing
It shows the evolution of an being. "Fossil record, history of life as documented by fossils, the remains or imprints of the organisms from earlier geological periods preserved in sedimentary rock." from https://www.britannica.com/science/fossil-record
<h2>
Answer:</h2>
The scientist started to study relationships among various groups of organisms <u>C. by using genetic analyses</u>.
<h2>
Explanation:</h2>
The following features were used to study about the relationships between different groups of organism:
- External morphology
- Similarities in structure
- Genetic analysis
- Chemical composition
The molecular similarities in the structure of RNA, DNA, and proteins help to establish the relationship of relationships between different groups of organisms. This was studied through testing the samples obtained by organisms using genetic analyses.
