the diagram below shows a food web in a woodland.

a food web diagram showing cornstalks with two arrows pointing away from it. one of the arrows points to the letter x and the other arrow points to a grasshopper. there are two arrows pointing away from the grasshopper. one is pointing to a baby sparrow and the other to the letter y. there is an arrow pointing away from the baby sparrow to a snake and an arrow pointing away from the letter x to the snake.

if a certain organism is a primary consumer, what best explains its position in the food web?

x, because organism x has the same role as the grasshopper
y, because organism y has the same role as grasshopper
x, because organism x has the same role as the baby sparrow
y, because organism y has the same role as the baby sparrow

Bisphenol a (often called bpa) is a chemical found in products that people use every day, from water bottles to food containers to children's toys. unfortunately, bpa leaches out of its many products and makes its way into our bodies. what are the health effects of bpa exposure? ongoing research is finding that elevated exposure to bpa can affect a wide variety of developmental and physiological processes, but one of the first studies of bpa's health effects came about because of a simple mistake in the lab. at a laboratory at case western reserve university in 1998, geneticist patricia hunt was making a routine check of her female lab mice. as she extracted and examined developing eggs from the ovaries, she began to wonder what had gone wrong. she noticed that many of the eggs showed problems with their chromosomes, and some had irregular amounts of genetic material, which can lead to miscarriages and birth defects in mammals. she learned that a lab assistant had mistakenly washed the plastic mouse cages and water bottles with a harsh soap, releasing bpa from the plastic. knowing that bpa is an endocrine disruptor, a chemical that can enter organisms and mimic hormones, hunt set out to discover whether it had adversely affected her mice.
