Asap, 10 points and brainliest! stick around if you can, i get confused easily and might ask for you to explain more, !

If you study the diagram, you will see that it looks like someone took a bite (in the shape of a small rectangle) out of a large rectangle. So to find the area of the complex diagram, we simply subtract the area of the small rectangle (the bitten off portion) from the whole large rectangle.

Area of large rectangle = 69 * 31 = 2139

Area of small rectangle = 23 * 12 = 276

Area of complex figure = area of large rectangle - area of small rectangle = 2139 - 276 = 1863 square meters

Hope that helps. Let me know if you have any questions.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
