'less'
Explanation
## Step 1The problem is about the basic principles of ecosystems and the relationships between different populations of organisms. In this case, we are discussing a food chain in a grassland ecosystem. ## Step 2If the population of long-tailed weasels decreases, the Great Horned Owls, which are predatory to the weasels, will have less available prey. This is because the weasels serve as a food source for the owls. ## Step 3This decrease in available food source will negatively impact the survival and reproduction of the Great Horned Owls. The reason is that with less food available, the owls will have a harder time surviving and producing offspring.## Step 4The concept being illustrated here is the principle of predation in food chains. Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. In this case, the Great Horned Owls are the predators and the long-tailed weasels are their prey.
