Because they are grouped in the same kingdom‚ the nine animal phyla share the same fundamental characteristics- they are multicellular‚ heterotrophic eukaryotes that obtain nutrients through ingestion‚ they lack cell walls‚ they have nervous tissue and muscle tissue‚ and they reproduce sexually and have a unique embryonic life cycle. However‚ the animal phyla have a great number of differences as well. Some are visible to the naked eye‚ while others are less obvious‚ and still more cannot even be

How Organism Evolved Physiologically Cassi Verkade How Organism Evolved Physiologically Organisms adapt to their environment but what happens when an organism’s surroundings and environment change? Physiological ecology is the study and understanding of that mechanism of living organisms and how living things work. Physiological ecology arises with an understanding of the influence of temperatures. Temperature‚ along with others‚ is one of the most important factors of Physiological ecology

When you think of an animal‚ you usually think of something like a cat‚ a dog‚ a mouse‚ or a tiger. All told‚ around 800‚000 species have been identified in the Animal Kingdom -- most of them in the Arthropod phylum. In fact‚ some scientists believe that if we were to identify all species in the tropical rain forests
