in a flock of ostriches there are two types: ones that run fast and ones that run slow. the fast ostriches 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. a flock of ostrich population will change over time?

• survival rate of the faster ostrich is higher, so their populations will increase, while the populations of the slower ostriches will decrease
• survival rate of the faster ostrich is lower, so their populations will decrease, while the populations of the slower ostriches will increase
• survival rate of the slower ostrich is higher, so their populations will increase, while the populations of the faster ostriches will decrease
• survival rate of the slower ostrich is lower, so their populations will increase, while the populations of the faster ostriches will increase

Explanation:

Los avestuces rápidos alcanzan hasta 48 mph, mientras que los chacales llegan a 38-40 mph. Los avestuces rápidos pueden escapar de los depredadores, por lo que su tasa de supervivencia es mayor. Los avestuces lentos no pueden escapar, por lo que su población disminuirá con el tiempo.

Answer:

Survival rate of the faster ostrich is higher, so their populations will increase, while the populations of the slower ostriches will decrease.
