AP Biology Summer Assignment Chapter 50.1: An Introduction to Ecology and the Biosphere Ecology is the scientific study of how organisms interact with the environment. When studying Ecology scientists want to know‚ where organisms live‚ why they live there‚ and how many are there. Ecology and environmental biology both stem from Darwin’s interest and observations upon the distribution of organisms and how they adapted to their specific environment. Darwin concluded that the environment interacting

Both Green algae and vascular plants have many similarities displaying this fact. Just a few of these similarities include that both groups have chloroplasts with chlorophyll

Hypothesis: Prey that is camouflaged in its habitat are harder to spot‚ and get to live long enough to pass on their genes which means the colors of the population that don’t fit in with the environment will eventually die out. Therefore‚ white will survive‚ and red will die out.

Introduction A key concept in evolutionary biology is that divergent selective regime will often generate and maintain some type of phenotypic diversity (Langerhans et al. 2003). This divergent selection can lead to differences in phenotypic expression either by a genetic differentiation or phenotypic plasticity (Levins‚ 1968; West-Eberhard‚ 1989: Robinson and Wilson‚ 1994; Orr and Smith‚ 1998; Schluter‚ 2000; cited in Langerhans‚ 2003). Such divergence is significant as it can influence microevolutionary

The study of the interaction between organisms and the environment; the connectedness between living systems and non-living systems on the Earth is called ecology. The term “ecology” which was coined by Ernst Haeckel comes from the Greek root words oikos logos literally meaning “the study of household”. Haeckel was referring to the interactions within the house of nature and we have used the word ecology (translated from the German Oekologie or Ökologie) to describe complex systems of life both extant

Evolutionary Biology vs. Creationism Evolutionary biology and Creationism are both alike and different in many ways. Evolutionary biology is known as an “interdisciplinary field”. That is because it is known to include scientists from a wide range of both field and lab oriented disciplines. Evolutionary biology includes scientist who have special training in mammalogy‚ ornithology‚ and herpetology. Creationism only has one creator‚ which is God. God is the one and only scientist and creator of

Biology Revision notes Ecology: 1) Ecosystems‚ sampling and population studies Population: All the individuals of a given species living together in the same area and at the same time. Community: Community: all the individuals of all the species living together in the same area and at the same time. Habitat: The area in which an organism lives within an ecosystem Niche: describes where an organism lives‚ what it does (its role)‚ what it feeds on and how it interacts with other organisms and the
