You decide to volunteer at a community garden and are assigned to tend six equally sized vegetable beds. Three of the beds contain only tomato plants, while the other three contain tomatoes as well as snow peas, bell peppers, cucumbers, okra, and broccoli. You work hard all summer and fall, tending the plants through insect attacks, diseases, and severe summer storms. You harvest vegetables every three days and start to notice a pattern. The mixed vegetable plots consistently produce 4 pecks (a unit of dry goods measurement) each at every harvest, while the tomato only plots produce between 1-6 pecks each at every harvest. The garden director notices the pattern as well, and knowing you are a biology student, she asks you for an explanation.

A conservation manager is planning to reintroduce collared lizards into an isolated glade in Missouri,
