What should I choose for my options?

I want to work with animals mainly, but I'm not sure what with animals. Either that or a meteorologist. My options forms for school need to be in next week and I'm so stuck:( we have to pick four options along with the compulsor subjects: English, maths, science, PE, short course RE. I've already decided to take German and Geography, but I'm confused on two other options. I was strongly considereing Human Health and Physiology, and I'm struggling to decide between Astronomy and Food Tech for my final option. I know that I should be choosing for myself as they will only effect me, but I need some help because I really enjoy astronomy, I love the stars and I also enjoy food tech:/ to be able to take Astronomy or Human Heath and Physiology, we must get at least a level 6 in Science, which is no problem for me. I'm still so confused though:/
