Which of the following statements correctly describes the relationship between biodiversity and sustainability? (1 point)
O Biodiversity and sustainability both increase when the number of species in an ecosystem decreases.
O Biodiversity and sustainability both increase when the number of species in an ecosystem increases.
O Biodiversity increases while sustainability decreases with an increase in the number of species in an ecosystem.
O There is no relationship between biodiversity and sustainability.
The statement that correctly describes the relationship between biodiversity and sustainability is, biodiversity increases while sustainability decreases with an increase in the number of species in an ecosystem.
What do you mean by Biodiversity?Biodiversity may be defined as the sum total of all the living organisms living in a particular ecosystem.
As the number of species increases, biodiversity also increases because both are directly proportional to one another.
While the species enhancement negatively impacts the sustainability of the environment.
Therefore, the statement that correctly describes the relationship between biodiversity and sustainability is, biodiversity increases while sustainability decreases with an increase in the number of species in an ecosystem.

Counting individualsMark-and-recaptureSamplingWhat is population size estimation?Population size estimation refers to the process of determining the number of individuals in a particular population. It is an important aspect of ecological and conservation research because it provides critical information about the status of a species and the health of an ecosystem.
There are several methods that can be used to estimate population size, including direct methods such as counting individuals, and indirect methods such as mark-and-recapture or sampling.
These methods can vary in their accuracy, practicality, and cost, and the choice of method often depends on the species being studied, the available resources, and the research objectives. Population size estimation is a key component of wildlife management, conservation planning, and biodiversity assessment.

Rainbow trout live in the rivers and streams of upstate New York. Rivers in this area are cold and have strong currents. If temperatures fall over time because of climate change, what is one variation that would likely help the trout to survive? Why? Write 1-2 sentences.(2 points)
Tolerance towards cold temperature and adaptabilities are the variation that help the trout fish to survive.
Which factor help the trout to survive?If temperatures fall over time because of climate change, the tolerance towards cold temperature is the one variation that would likely help the trout to survive because only those organisms survive in cold temperature that have good tolerance and various adaptation towards cold temperature.
So we can conclude that tolerance towards cold temperature and adaptabilities are the variation that help the trout fish to survive.

Which individual is a producer?
a host who seats customers in a busy restaurant
O a mother who demands quality produce for her family
O a farmer who grows only what his family needs to survive
© a student who builds a bookcase from bricks and boards
A
The individual who can be referred to as a producer is a farmer who grows only what his family needs to survive. Thus, the correct option is C.
Who is a producer?In a food chain, the producers are the organisms which can produce their own food without the help of other organisms. Generally, plants are called the producers of an ecosystem because they produce their own food and gain sustenance from the process of photosynthesis. The process of photosynthesis allows plants to produce food such as glucose (carbohydrate) which is a sugar energy. The breakdown of glucose results into formation of energy in the form of ATP (Adenosine Triphosphate).
The farmers can be referred to as producers as they are growing their own food.
Therefore, the correct option is C.

3 paragraph summary (I'll give brainlist if you do it correctly)
Answer:
alright bet I got this
Explanation:
Have you ever wondered what can happen to those plastic bottles you toss away? How do they decompose? What happens to them? Its simple really, they get eaten! No, not by people of course they are eaten by a tiny critter called a wax worm. The wax worms earn their name because they are often found living in beehives where they eat the beeswax.
Wax worms much like mealworms are used to break down things that would normally be endangering to our environment. These seemingly useless little animals do a whole lot for our environment especially with the amount of waste we produce! They really are a tiny secret hero to todays pollution problem.
After quite a few studies scientists are still unsure on how was worms can breakdown plastic with their tiny bodies but they appreciate the work these little recyclers do. They have a lot of theories on how these worms do this one of the theories is that bacteria can break it down, another theory is that enzymes in the worms intestines break down plastics. Though scientists believe it will take a while to figure this out they enjoy studying and learning more about this tiny helper.
