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:water erodes the earth by passing over rock and thinngs many times, as in a river, the water slowly washes away the rock turning it into sediment or silt.
Explanation:
Answer:Hope this helps :) if so pleas could you mark brainliest:) enjoy!
Explanation:
The cycle of water erosion has been here since forever thanks to the rain rivers, ponds lakes, the sea and the ocean because it first starts off with the rain then the rain fills up the lakes and pond and start rivers and the rivers lead to the sea and ocean and from there the water evaperates then it rains again and the lakes and ponds help with the evaporation.

The following table shows the distance from the sun of some unknown planets of equal mass.
W 1.5 AU
X 0.723 AU
Which of the following best explains which planet revolves at a faster speed?
A.) Planet X, because the sun pulls it with a greater force.
B.) Planet W, because the sun pulls it with a greater force.
C.) Planet W, because the gravitational force is weakened by distance.
D.) Planet X, because the gravitational force is strengthened by distance.
Answer:
Option D.) Planet X, because the gravitational force is strengthened by distance.
Explanation:
As we know from Kepler's law , the planets that are closer to the sun move at a faster rate in comparison to those planets that are far because of high gravitational force.
According to the question,
both planets have equal mass. Plant W is at 1.5 AU and planet X is at 0.723 AU distance from the sun.
So, planet X revolves at a faster speed because it's shorter distance from the sum as comparison to planet W, strengthened the gravitational field.
Thus, Option D is the correct answer.
