Biological domain Animalia is <u>heterotrophic</u>
Answer: Option B
<u>Explanation:</u>
The Animalia kingdom follows the heterotrophic mode of nutrition which means it depends on other organisms for their nutrition while autotrophs produce their own food. Carbon is the main source of energy. The heterotrophs get carbon from consuming these organic resources.
The cells are eukaryotic and they are multicellular organisms.They do not have a cell-wall. They intake large molecules and using their different organ system break down the food into simpler substances which provides nutrition and energy for the organism to survive.
Answer:
Ecological niches allow species to exist in their environment. Under the right conditions, the species will thrive and play a unique role. Without the ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.
If two species occupied the same niche, they would be competing for the exact same resources. The competitive exclusion principle states that one of the species would drive the other to extinction.
