In an ecosystem, if the last three animals of a species are all females, the species will become extinct because it takes a male and a female to reproduce .
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answer: The wind erodes the earth by moving pieces of it every which way.
Explanation:
Every patch of air carries hundreds of thousands pieces of dirt sand and chunks of earth. When the wind changes course it will slowly pick up more and more and until an indent will form. This is also how sand dunes are made.
Answer:
If the wind constantly pushes a rock, eventually the sides will start eroding, and the wind will cause it to break and erode.
The blowing wind constantly changes the earths surface by moving rocks, and breaking them.
by the wind constantly pushing sand on top of each other in one place.

Write a paragraph (5-8 complete sentences) answering the prompt＂How does the availability of resources in ecosystems impact ecosystems?＂
5-8 Sentences on: "How Does The Availability Of Resources In Ecosystems Impact Ecosystems?"
Changing out natural resources in our environment can affect the whole entire ecosystem. Ecosystems can change throughout time but the change may or may not affect the ecosystems. But according to research, if the change is too fast the whole ecosystem can be destroyed. An imbalanced or damaged ecosystem can lead to problems. Certain resources play an important role such as sunlight and water, we need resources to survive and can also help living creatures. These resources impact animals, plants, and insects/bugs.
P.S If you need more sentences I will edit my answer!

Answer:
Threatened Species: A threatened species is a species at risk but not yet endangered. California sea otters were classififed as a threatened species. Laws were passed to protect the otters and now they have increased their population size.
Invasive Species: One of the main causes of extinction and endangered species is the introduction of an exotic species. New exotic species are called invasive species. Invasive species can disrupt food chains, carry disease, prey on native species directly, and out-compete native species for limited resources, like food.
Extinction: If a population decreases too much in numbers, they disappear. Extinct species mean that the species has died out and no individuals left. An example of extinction: New Zealand was once home to a bird called the Giant Moa. Humans settled as their population increased the Moa population decreased. The species is now extinct.

a. to reach mineral ore deep below the surface of the earth
b. to reach mineral ores on the surface of the earth
c. to drain underground lakes where minerals are found
d. to create strip mines and quarries below the surface of the earth
The function of tunnels and passageways in subsurface mining to drain underground lakes where minerals are found. option C is correct.
What is subsurface mining?Subsurface mining is the process in which mineral ores are too deep to extract at with this mining techniques, subsurface mining methods are used .
An advantage and good thing of subsurface mining is that it will not disturb land than surface mining it only disturbs less than one-tenth the surface amount of land as surface mining and the method.
Therefore, the function of tunnels and passageways in subsurface mining to drain underground lakes where minerals are found. option C is correct.

HELP IMPORTANT TEST!! Why must animals eat food but plants do not eat food? A: Plants do not appear to eat, but they do actually eat nutrients in the soil. Animals must eat to obtain food that they can't get from the soil. B:Plants make their own food through photosynthesis. Animals must eat because they cannot make their own food. C: Plants use photosynthesis to make their own food instead of eating. Animals eat plants because they like the taste of certain fruits. B: Plants make their own food through photosynthesis, so they do not eat. Animals eat because the energy they make themselves is enough to live but not grow. By eating, they can grow big and strong.
