Forests would be able to survive a disease better.
<h3><u>
Explanation:</u></h3>
Many studies have taken place for many years to determine what type of ecosystem can best survive diseases effectively. A recent study has concluded that the forests are the viable ecosystem which can survive a disease better then any other ecosystem; followed by grasslands as the second best.
The study states that the chances of forests are better as the ecosystem contains many different species of trees and plants. The mix of several species in an ecosystem helps in surviving climate changes, pests and severe diseases. According to the study, the diversity of different biological species have a better rate of production than an environment which has only one species in it. The biodiversity will help produce the amount of energy that would best suit the needs of population.
Answer: Producers
Explanation: Producers are autotroph, which means they make their own food, like plants.
Similar to the other types of muscle, smooth muscle contraction is caused by the sliding of myosin and actin filaments over each other. Calcium initiates contractions in a different way in a smooth muscle than in a skeletal muscle.
Smooth muscles use less energy to generate the given amount of force, can substain contractile force without fatigue & uses calcium from the sarcoplasic reticulum & extracellular space.
