The meteorite was probably 1<span>0 to 15 km (6.2 to 9.3 mi) wide</span> and affected the entire planet through a proces called "impact winter". As the name suggests, an impact winter is a period of low temperature produced by a huge cloud of ash and dust that blocks sunlight. Since sunlight is essential for plants to survive, if the sun rays are blocked by this cloud, all animals that depend on those plants (including dinosaurs) will die. The meteorite could have created such a cloud upon hitting the earth.
Answer:
49.54
Explanation:
Given parameters:
Number of organisms in original habitat = 4695
Number of organism in new habitat = 2326
Solution:
To find the percentage of the organisms in the new habitat that has migrated to the new habitat, we use the expression below:
% of the population in the new habitat = \frac{number of organisms in new habitat}{number of organisms in original habitat} x 100
% of the population in the new habitat = \frac{2326}{4695} x 100 = 49.54%
The answer is “d” (1,000 kcal). As the trophic level increases energy is decreases by 10 times that of the previous level. If a system has 10,000 kcal, then the primary consumer have 10 times less (10,000/10) which is 1,000 kcal. The secondary consumers have 100 kcal and the tertiary have 10 kcal. Only 10% of the energy at each trophic level goes on to the next.
