The above statement is true.
Heme iron is found only in meat, poultry, seafood, and fish, so heme iron is the type of iron that comes from animal proteins in our diet. While the non-heme iron, by contrast, is found in plant based foods like grains, beans, vegetables, fruits, nuts, and seeds. However, it is also found in animal products such as eggs or milk/dairy and it also comprises more than half the iron contained in animal meat.
The greenhouse filled with air containing more carbon dioxide than the normal air will promote the growth of the plant by increasing the rate of the photosynthesis. The water loss by the process of transpiration is reduced considerably, and the water-use efficiency is increased. This will result in a elevated growth of the greenhouse plants.
Hence, the answer is 'the photosynthesis rate will be increased which will increase the plant growth'.
<span>Decomposers are organisms such as ants, earthworms, bacteria an fungi that break down organic matter like dead and decaying plants and animals. Decomposers break the material down into its mineral components and returns it to the soil. If decomposers are absent in this ecosystem there would be no recycling of nutrients. Forest plants would not have available minerals to grow and productivity levels would fall significantly. </span>
