Looking at this quickly, 3 or 4 out of 6. Mainly be more specific, e.g. don't say "to make food in order to live", but e.g. "to produce glucose, which is needed for both aerobic and anaerobic respiration in order to produce energy in the form of ATP"

A small mistake...animals don't actually take in Carbon Dioxide...they breathe in Oxygen (ventilation) and convert oxygen and glucose into carbon dioxide and water (and energy) via aerobic respiration. The animals then breath out the carbon dioxide.

Thank youu for being honest 💕 What is glucose? And aerobic and anaerobic? Sorry havent gone over this :|

3 or 4 valid points so I would say 3/4 marks.
Also maybe mention the fact that microorganisms are responsible for the decay of plants/animals...

Glucose is C6H12O6, which forms your "blood sugar" for example. It is the fundamental sugar of nature.
Aerobic = using oxygen. The equation for aerobic respiration is C6H12O6 + 6O2 -> 6CO2 + 6H2O + 2900 kJ energy per mole of glucose (if you haven't done moles yet in chemistry then you will in the final year of your GCSE course).
Anaerobic = without oxygen. The equations for this are:
in animals: C6H12O6 -> 2C3H6O3 + 120 kJ energy per mole of glucose. (Notice that this is much less efficient than aerobic)
in plants: C6H12O6 -> CH3CH2OH + 2CO2 + energy (the exact amount will vary). Notice that CH3CH2OH is ethanol (the "alcohol" that one can drink), if you haven't done alcohols in chemistry yet.

Thank you so much ❤️❤️ Also you know this question how many marks would you give it Name:  ImageUploadedByStudent Room1456949212.109464.jpg

The 2 mark one gets a full 2 marks. In the 3 marker, perhaps also point out that in 1849, more women actually died in Ward A (the one with antiseptics etc.) rather than Ward B, although it's only a 0.1 percentage point difference.

Also on another note, your exam board seems significantly easier than the Edexcel IGCSE that I do.

I would give it 3, possibly 4, marks too. As the others above mentioned, your answer needs to be more specific e.g instead of saying plants take in CO2 to you could reword it to say something like plants absorb CO2 from the atmosphere which is important to carry out photosynthesis and produce oxygen and by-products
