Detailed explanation-1: -Some emus run fast (between 30-35 mph) and other emus run slower (between 20-25 mph). Dingoes are the main predators of emus and at their absolute fastest can reach speeds of up to 30 mph. Emus lay between 30-50 eggs a year, but only 20 of those eggs will live long enough to mature into their own reproductive age.
Detailed explanation-2: -In ostriches, there are 2 types: ones that run fast and those that run slowly. The fast birds can reach up to 40 miles an hour. Jackals love to eat ostrich, and they can reach speeds of up to 35-40 miles per hour.
Detailed explanation-3: -Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Detailed explanation-4: -An adaptation is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment.
Detailed explanation-5: -According to Charles Darwin’s theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
