1) This includes two leaf-feeding beetles, one root-boring weevil and one flower-feeding weevil. ... calmariensis are leaf-eating beetles which seriously affect growth and seed production by feeding on the leaves and new shoot growth of purple loosestrife plants.
Hi there!
In order to do fossil comparative anatomy and branching diagrams to explain the evolution of organism, scientists use <u>radiocarbonation </u><u>method</u>.
Explanation:
Carbon-14 can combine with oxygen in the atmosphere to create carbon dioxide, which is then absorbed by plants and makes its way through the food chain. The amount of carbon-14 in living plants and animals matches the amount in the atmosphere, but when plants and animals die, they no longer absorb carbon-14.
Because radiocarbon has a known rate of decay, the scientists can now determine about how long it has been since the plant or animal was alive. <u>The lower the amount of radiocarbon, the older the object.</u>
(Sometimes, C-12 is also used)
For the first question is that crabgrass because in the process of secondary succession a forest fire burns down a forest then grasses grow back, then annual flowers bloom and eventually trees begin to grow so crabgrass is the initial stages of secondary succession.
Answer:
A.) for souvenirs
Explanation:
Tourists are interested in mining corals mainly to get souvenirs, since corals are known to be pretty and would be a "good" souvenir because of that.
Tourists would not be interested in mining corals to build roads, get protection, or get bone grafts because tourists are just interested in visiting a place and getting souvenirs from it.
The answer is predation because when a living organism eats another living organism (predator eating prey) it is predation and also the cycle of life. (Like how we eat our foods in our everyday life lol)
