Yes but you have to make sure you get your daily need of protein through other food sources. (our daily need: 0,8 to 1 gram protein per kilogram of body weight)
Protein is one of your body's important building blocks and must be incorporated in your daily diet for optimal health.
Most people get their daily need through meat, fish and dairy. But most plants actually contain protein, some even exceed the protein quantity of beef, chicken, fish, and dairy.
If you still eat fish and dairy then there should be no problem in meeting your daily need. But if you decide to become a vegetarian or vegan you should add more plant-based protein to your diet. Actually even if you eat meat or fish you should reduce your intake and add more plant-based proteins to your diet.
They provide a wide range of healthy nutrients such as antioxidants, fiber, vitamins, and minerals; and most of them neutralize acid-forming metabolites.
Here are a few examples of foods rich in plant protein: avocado, goji berries, chia seeds, flax seeds, Brazil nuts,almonds, beans, quinoa, etc.

You don't need meat in your diet, and you won't get sick from not eating it, but there are some risks to not eating meat. What it provides for you is protein and a lot of people who don't eat meat don't get enough protein. If you plan to go vegetarian, make sure you get plenty of protein in your diet because you can get sick from lack of protein.
They can survive indefinitely as long as the food is nutritious and they have plenty of water.
No. Puffer fish can only survive in the ocean.
Only when they are eating them.
eating only plants
The only way that they can survive is by eating and hunting antelope.
Only if you don't mind it eating the fish !
of course they can! usually fish have 100 babies and only 20 survive!!!!!
To make a hypothesis on this subject, think of what background knowledge you have on fish and their eating habits. Then, make an educated guess. Does rice grain have sufficient vitamins, energy, and supplements a fish needs? Think of it like this: humans need vegetables, meet, different vitamins, water ect. in order to survive. Fish need certain components in their diets in order to survive, also. Do you think rice grain would be enough? Depending on the fish type, your hypothesis may vary. Keep in mind no hypothesis is wrong. It is important you explain why you think fish can survive on rice grain, or why they cannot survive on rice grain. Start your hypothesis like this: If fish were only fed rice grain, then they would not survive because rice grain isn't sufficient enough for their diets.
the fish will not survive depending on how much and how long
Nut-crazy. There is no word for someone who only eats nuts, because only eating nuts does not supply you with the necsisary nutrients in order to survive/thrive.
They can but only for a short amount of time.
You cannot survive for even a season on only steamed rice. I highly doubt that you can survive on only steamed rice for a month.
