Answer:
Radiocarbon dating
Explanation:
Radiocarbon dating is a technique for determining the age of carbon-based materials derived from live beings. By measuring the quantity of carbon-14 in a sample and comparing it to an internationally accepted reference standard, an age may be determined. Radiocarbon dating is based on the basic principle that all living organisms absorb carbon from the atmosphere and food sources around them, including a small quantity of naturally radioactive carbon-14. When a plant or animal dies, it stops absorbing carbon, but the radioactive carbon it has stored decays.

State two arguments people might make for not preserving botana curus.
Answers
The two-argument people might make for not preserving botana curus are they take a long time to grow, so it may not be worth the effort; there are organisms that are similar, and it may be expensive.
What is botana curus?Botana curus is a precious plant because it yields Carol, a substance that can be used to treat cancer.
Curol cannot be manufactured in a lab. Botana curus grows slowly and is an endangered species, so its ability to produce large amounts of Curol is limited.
Thus, the two arguments are they take a long time to grow, so it may not be worth the effort and there are organisms that are similar, and it may be expensive.

Changes in ecosystems can be attributed to natural causes, such as natural disasters, seasonal variations in climate, currents, and tidal activity. Many of these changes can affect the amount of food resources available in an ecosystem. Research one natural change that currently affects or could affect the aquatic ecosystem you chose. Use your food web model to explain how this change can affect the competition of food resources in your aquatic ecosystem.
Answers
The reduction of food sources results in the competition of food resources in the aquatic ecosystem.
How natural disaster can leads to the competition?Severe storm occurs in the water which adversely affected the aquatic ecosystem. This change can affect the competition of food resources in your aquatic ecosystem because the food on which the aquatic animals feed is destroyed by the storm. So less food is available for the organisms which leads to competition between organisms.
So we can conclude that the reduction of food sources results in the competition of food resources in the aquatic ecosystem.
