1. The Burmese python is an invasive species in the Everglades ecosystem. This means its numbers increase dramatically due to lack of natural predators. The python is feeding on small mammals such as rodents that feed of egg of animals such as the turtles. This, therefore, causes a ripple effect on the food web in the ecosystem e.g dramatically increasing turtle population.
2. Due to the lack of natural predators in the ecosystem, the Burmese python causes an imbalance in the Everglade ecosystem. They reduce the biodiversity of the ecosystem hence diminishing the quality of natural resources.
3. The number of Burmese pythons can be regulated by introducing a predator in the Everglade ecosystem. Examples of animals that can prey on the snake are eagles, pumas, lions, crocodiles, cobras, and humans. This will reduce the numbers of the Burmese python and restore the balance in the ecosystem.
Herbivores depend on plants for food. Carnivores depend on herbivores. Omnivores depend on both plants and animals. Plants depend on decomposed animals and plants for food
Answer:
The correct option is A. Coal use in steam engines led to easier access to goods.
Explanation:
Coal is used in steam engines as a fuel. Coal is one of the cheapest source of energy and hence it has been serving mankind with various benefits since a long period of time.
The coal-based steam engines played a very important role in the developments made during the Industrial Revolution. Many industries started using coal as a power material and made progress.
The steam engines made it possible to transfer goods from one place to another very easily. As coal was a cheap source, hence trading of goods by steam engines was not very costly.
