Hey there, curious minds! Can you help Avery, Lily, and Abigail figure out the main difference between a food chain and a food web?

• A food chain is more complex than a food web

• A food web includes only producers and consumers

• A food chain is a single pathway, while a food web consists of multiple pathways

• A food web is linear, while a food chain is interconnected

Imagine you're a scientist like Aiden, studying the factors that affect population size. Which of the following is a density-dependent factor that Aiden might discover?

• Natural disasters

• Climate

• Disease

• Temperature

Imagine Zoe and Kai are exploring a mysterious island. They stumble upon a sign that reads, "Beware of exceeding the island's carrying capacity!" What does "carrying capacity" mean in this context?

• The maximum number of individuals an environment can support

• The rate at which a population increases

• The number of offspring produced by an individual

• The average lifespan of individuals in a population
