As humans‚ we are the most dominant species in the world. We have the ability to walk upright‚ grasping thumbs‚ and large brains. This helps us to live and be successful on earth. But‚ these advantages we have didn’t happen overnight‚ they occurred during the hominine evolution. The skull‚ neck‚ spiral column‚ hip bones‚ and leg bones of the early hominine species changed shape in ways that later enabled species to walk upright. The evolution of dipedal‚ or two-footed‚ locomotion was very important

Water-holding frog | Fungi | There are three major categories of all living organisms’ producers‚ consumers and decomposers. Producers‚ also called autotrophs‚ in an ecosystem consist of mostly plants and some bacteria and algae that use photosynthesis to catch energy by sunlight‚ carbon dioxide‚ water to create carbohydrates. Consumers‚ also called heterotrophs‚ include animals‚ bacteria‚ and fungi that get their energy consuming other organisms. Decomposers are organisms that break down organic material

However‚ conceptually it will be a little easier because the concepts learned in Chapter 9—namely‚ chemiosmosis and an electron transport system—will play a central role in photosynthesis. 1. As a review‚ define the terms autotroph and heterotroph. Keep in mind that plants have mitochondria and chloroplasts and do both cellular respiration and photosynthesis! Concept 10.1 Photosynthesis converts light energy to the chemical energy

chemoautotrophs‚ a new theory was instilled. The discovery of chemosynthesis in bacteria gives new insight into how life may have been formed on earth. The theory currently accepted and taught is that photosynthesizers came first‚ and were followed by heterotrophs. This theory‚ however‚ was formulated before the discovery of Chemosynthetic microbes. This new synthesis process has questioned this theory‚ with solid arguments. Information that supports the theory that chemoautotrophs were the first forms of

2.1.3 A food chain shows the flow of energy from one organism to the next. A food web is a complex network of interrelated food chains. Producers (autotrophs): manufacture their own food from simple inorganic substances (including sun light). Consumers (heterotrophs): feed on autotrophs or other organisms to obtain energy. Example of different feeding levels: Trophic level 1 – producer e.g. grass Trophic level 2 – herbivore (primary consumer) e.g. grasshopper

Cells are the basic functional units of all organisms. Cells are the smallest unit of life and are often called the "building blocks of life". The distinction between prokaryotes and eukaryotes is considered to be the most important variation among groups of organisms. Eukaryotic cells contain membrane-bound organelles‚ such as the nucleus‚ while prokaryotic cells do not. The differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts‚ the

Its leaves look pale and weak. Plant may not even flower properly. Such a situation is an indication‚ that the plant may not be getting all that is required for normal growth and development.
