Algae are small photosynthetic organisms found in aquatic ecosystems. Their cells produce a kind of oil. Scientists learned how to extract the oil to create fuel, which can be used in place of fossil fuels. Scientists think algae can produce 60 times more oil per acre than plants, like corn, that are commonly used to produce biofuel.
To produce algae oil, very large ponds were built for growing algae. However, scientists soon made two discoveries.
As the algae grew, it formed layers at the pond surface. These layers crowded and shaded one another.
Many insects and other consumers frequently entered the ponds.
Based on the two discoveries, what would likely be a problem for algae oil production?
A.
Crowding reduces access to food, so it makes algae less able to take in sugar and produce oil.
B.
Insects feed on algae, so all of the energy stored in algae oil is converted back into light energy.
C.
Consumers feed on algae, so the energy stored in algae oil is permanently lost from the environment.
D.
Shading reduces access to sunlight, so algae produce less sugar and are less able to store energy.
Answer:
C.
Consumers feed on algae, so the energy stored in algae oil is permanently lost from the environment

Why is it important that people use fewer non-renewable resources and more renewable resources?
Your Opinion and Evidence
Answer:
well I think that it I'd important to use more renewable resource because using much of non renewable sources can cause a shortage of it. it is non renewable
Answer:
Harnessing renewable resources tends to be better for the environment. Non-renewable resources such as fossil fuels produce vast amounts of greenhouse gasses when they are burnt and this contributes to acid rain, climate change and other ecologically harmful effects. By contrast, wind and solar energy do not produce these dangerous gases.

The drawing shows the shapes of trees growing on their own and inside a forest. The trees are of the same species. Describe the differences between the tree growing on its own and the trees inside the forest. Suggest reasons for the differences you have described
Answer:
The trees inside the forest are taller and have less leaves than the tree on its own. You can also see the trees in the forest are deciduous and luscious, opposed to the tree shrub living on its own.

Help me with this bs packet thing
Can someone please help me? :(
Answer:
B
Explanation:
only option that reduces the use of motorized vehicles
Answer:
B. Building new bike paths in the city.
Explanation:
This is the most possible way since...
If there are more bike paths, then there are more ways that they are going, which means more usage of them. If there is going to be more usage of them, then there is going to be less usage of cars in the city.So hence, your answer is B. Building new bike paths in the city.
Now, let's look WHY are the other ones NOT the right answer:
A. Widening roads throughout the city
This just won't do anything, rather, it will make drivers more want to go on the road since the roads are wider and easier to drive on.
B. Buliding new bike paths in the city
this is the right answer, for explanation, look above
C. Expanding the city into nearby areas
There is no use of the city being expanded, that way, if you live in one corner of the city, and your office is in the other side, then you wouldn't want to use your bike, you'll want to use the car, which is what you don't want to do.
D. Raising the price of riding the city bus
Not helpful either, this won't help that much, since 1 job will lose, 2nd, people who don't know how to drive or are pregant(probably can't ride a bike) won't be able to travel. And last, it's just so selfish..
So from all these conclusions, we can see that B is truly the answer.Buliding new bike paths in the city.-------------------------------------------------------------------------------------------------------"The beautiful thing about learning is that no one can take it away from you!" B.B.King

What are ocean waves?Ocean waves are the result of the interaction between the ocean and the wind. They are the most visible and powerful manifestations of the Earth's oceans. Ocean waves vary in size, shape, and speed, depending on the wind's strength, duration, and direction. They can range from small ripples to massive swells and can travel thousands of miles before breaking on shorelines.
The energy of ocean waves is harnessed for various purposes, such as surfing, fishing, and generating electricity through wave energy converters. However, ocean waves can also be destructive, causing erosion and flooding in coastal areas during storms.
Ocean waves play a crucial role in regulating the Earth's climate by transferring heat and energy from the tropics to the poles. They also help distribute nutrients and oxygen to marine life, and their movement influences the ocean's circulation patterns.

How did green algae come about
Answer:
Green algae grow at the edges of a glacial lake in Wales. Hundreds of millions of years ago, similar algae adapted to survive temporarily outside of the water may have kicked off the evolution of green land plants.
Algae didn't always hang out in the seas, but one fateful day, about a billion years ago, a simple bacterial cell swallowed a cyanobacteria cell, writes Ed Yong at The Atlantic. This chance occurrence allowed the bacteria to produce energy from the sun, a process known as photosynthesis.
