This question is incomplete because the images a section 2 are not given. I searched for the complete question but could not find it. However, based on my knowledge and the characteristics of the tundra this is the answer.
The correct answer is C. The climate is harsh, which limits the number of species that can live there.
Explanation
The tundra is the name of an ecosystem that occupies a fifth of the earth's surface, mainly in the northern hemisphere, this is characterized by having a frozen subsoil that limits the emergence and growth of natural vegetation and trees. This ecosystem is the coldest on the planet due to its location near the poles, its landscape is characterized by a layer of snow that covers most of the ground. In addition, the climatic conditions are extreme, which limits the number of plant and animal species that can live there. According to the above, the correct answer is C. The climate is harsh, which limits the number of species that can live there.
Size, density, and growth rate are the three main ones. There is also dispersion, age structure, and survivorship. Hope this helps!
Answer:
The calories Anna consumed for dinner is 315 kcal (300kcal). The calories that came from proteins is 108 kcal (100kcal).
Explanation:
Macronutrients are nutrients such as protein, carbohydrates, and fat that provide the energy required for the normal functioning of the body. Usually, the energy obtained from macronutrients is expressed in calories. Each gram of protein provides 4 kilocalories while each gram of fat provides 9 kilocalories. Carbohydrates per gram also provide 4 kilocalories.
Here, Anna consumed 7 grams of fat (in salmon)
, 36 grams of carbohydrates (in sweet potatoes and asparagus) and 27 grams of protein (in salmon, sweet potatoes, and asparagus) for the dinner.
Therefore, total calories in 7 grams of fat is 
kilocalories.
Total calories in 36 grams of carbohydrates is 
kilocalories.
Total calories in 27 grams of protein is 
kilocalories.
Therefore, the total calories Anna consumed for dinner is 
kilocalories i.e., 
kcal.
The calories that came from proteins is 
calories i.e., 
kcal.
I believe that the answer would be B. Ichthyosaurs. Hope this helps :)
