Chapter 5 Plant Growth and Development
... First let’s define some common terms such as annual, perennial, grass, forb and shrub. An annual plant is one that starts from seed each year and completes its life cycle in one year. A perennial plant survives and grows for several years. While perennials may produce seeds, they invest a certain am ...

Research paper: Food webs in the ocean: Who eats whom and how
... Over 100 food webs have been published for marine ecosystems to describe the transfer of food energy from its source in plants, through herbivores, to carnivores and higher order predators. The webs suggest that the lengths of the chains that form food webs are typically short (3–4 links), and that ...
