The best and most correct answer among the choices provided by your question is the second choice or letter B. <span>Animals obtain carbon from plant and animal consumption.
</span>With the help of the Sun, through the process of photosynthesis, carbon dioxide is pulled from the air to make plant food from carbon. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon<span> from their food too.

Plants have three main tissue system.
1. dermal tissue which is the protective outer covering of a plant. In young plants it consists of single layer called epidermis. A waxy cuticle often covers epidermis and protects against water loss. In older plants, dermal tissue may be many cell layers deep and may be covered with bark.
2. vascular tissue supports the plant body and transports water and nutrients throughout the plant. The two kinds are xylem, a water-conducting tissue, and phloem, a tissue carries dissolved nutrients. Plant fibres such as cotton and linen are produced by the vascular tissue systems of plants. It contains many long, slender cells that form long tubes and have walls that are reinforced by lignin. These characteristics are similar to those of fibres such as cotton and linen. neither dermal or ground tissue consists of cells with these characteristics.
3.ground tissue produces and stores sugars and helps support the plant. It consists of parenchymal cells, collenchyma cells and Sclerenchyma cells.
Answer:ryanodine receptor, or RYR) in the sarcoplasmic reticulum (SR), causes opening of the RYR. In cardiac muscle, opening of the L-type calcium channel permits influx of calcium into the cell
