A variety of plant populations can be found in a prairie. What would be the most likely effect on a plant populations if there was a significant decrease in rainfall? A- Competition for water among the plants would decrease B-Competition for water among the plants would increase C- it would increase the ability all the plants reproduce D-it would have no effect on the plant populations.

Answers

The most likely effect on plant populations in a prairie if there was a significant decrease in rainfall would be an increase in competition for water among the plants. So, the correct answer would be B - Competition for water among the plants would increase.

What is a plant population?

Plants are dependent on water for a variety of processes, including photosynthesis, growth, and reproduction. In a prairie ecosystem, different plant species coexist and comete for limited resources such as water, nutrients, and sunlight. A decrease in rainfall would lead to a reduction in the available water supply, which would result in increased competition for water among the plants. As water becomes scarcer, plants will need to adapt to survive. Some plants may be better able to tolerate dry conditions or have deeper roots that can access water from deeper in the soil.

Hence, So, the correct answer would be B - Competition for water among the plants would increase.

Help if you know about overfishing. What two suggestions are given to help stop overfishing?!

Answers

Answer:

YOU CAN HELP STOP OVERFISHING

The world’s oceans are so big we thought for a long time that there was nothing humans could do to hurt them. Now we’re facing an imminent and global collapse of our fisheries, projected to happen as early as 2048, thanks to overfishing, wasteful fishing practices and massive overconsumption. But, there are a few key tried-and-tested solutions to overfishing that have been successfully implemented around the world. The trick is to scale these solutions up to a global scale, encouraging countries that have originally been resistant to helping and get them onboard, and supporting countries that don’t have the means to update their fishing policies themselves.

Here is what needs to happen…

CREATE MORE MARINE PROTECTED AREAS

Currently, less than two percent of the world’s oceans are protected in marine parks; and less than one percent of the oceans are protected from any kind of fishing. More no-catch zones must be established to allow fish populations and their ecosystems to recover and replenish themselves to ensure fishing for future generations.

The Marine Conservation Institute wants to increase that number tenfold, and have ten percent of our oceans become Marine Protected Areas by 2020. We would like to see 20 percent of the ocean protected to ensure increased healthy fish stocks in the future.

STOP TRAWLING

Trawling drags huge nets through the ocean that scoop up every animal and the ecosystem in its pathway, resulting in massive wasteful bycatch – dead fish are returned to the sea because they weren’t the target fish. We don’t have that kind of sea life to waste. Though there are many programs that focus on decreasing by-catch, and worldwide there are small regions where bottom trawling is banned or limited, these measures aren’t enough. Trawling needs to be banned outright.

Facing depleted fish stocks with an imminent and complete collapse, the Chinese government imposed a trawling ban in Hong Kong’s waters that took effect in December 2012. They did this by buying fishing vessels fitted for trawling, and supporting deckhands who’d be affected by the reduced amount of fish caught. Bans like this in the waters of Alaska, Chile and elsewhere are being fought for by environmental organizations. They need our help!

WORLDWIDE CATCH SHARES

Catch shares is a system of fishing management that is proven to allow fish stocks to replenish, while saving the livelihoods of fishing communities by preventing a sudden collapse. A total allowable catch is established, using scientific data about the health of fish stocks and the environment in a certain area, and catch shares are licensed out to each fishing business telling them exactly how much of each seafood species they’re allowed to catch.

Using catch shares makes seafood more valuable, meaning a higher, more predictable profit for fishermen, while protecting the environment. As opposed to limiting the time of a fishing season—driving fishermen on a mad dash to make their living in a short time and use trawling or other unsustainable fishing methods to do it—catch shares foster communication and stewardship.

A study of American and British Columbian catch shares systems found that over a decade, the total allowable catch increased 19 percent, by-catch decreased by 66 percent, and fishermen made 68 percent more money while having one-third fewer accidents on the job. And 100 percent of fishing businesses complied, rarely going over their limit. It’s a proven system that needs to be implemented worldwide, and strengthened where it does exist, like the Common Fisheries Program in Europe or on the Pacific Coast of the US and Canada.

Where does the moon get its light from?

Answers

Answer:

The moon shines because its surface reflects light from the sun.

Explanation:

Answer:

The sun

The moon shines because its surface reflects light from the sun. And despite the fact that it sometimes seems to shine very brightly, the moon reflects only between 3 and 12 percent of the sunlight that hits it. The perceived brightness of the moon from Earth depends on where the moon is in its orbit around the planet.
