STANDARD B3: INTERDEPENDENCE OF LIVING SYSTEMS AND THE ENVIRONMENT
Students describe the processes of photosynthesis and cellular respiration and how energy is transferred through food webs. They recognize and analyze the consequences of the dependence of organisms on environmental resources and the interdependence of organisms in ecosystems.
L3.p1 Populations, Communities, and Ecosystems (prerequisite)Organisms of one species form a population. Populations of different organisms interact and form communities. Living communities and the nonliving factors that interact with them form ecosystems.

Amphibians and Reptiles - This event will test knowledge of amphibians, turtles, crocodiles, and reptiles.

Ecology - Students will answer questions involving content knowledge and process skills in the area of ecology and adaptation in featured biomes.

L3.p2 Relationships Among Organisms (prerequisite)Two types of organisms may interact with one another in several ways; they may be in a producer/consumer, predator/prey, or parasite/host relationship. Or one organism may scavenge or decompose another. Relationships may be competitive or mutually beneficial. Some species have become so adapted to each other that neither could survive without the other.

Amphibians and Reptiles - This event will test knowledge of amphibians, turtles, crocodiles, and reptiles.

Disease Detectives - Students will use their investigative skills in the scientific study of disease, injury, health, and disability in populations or groups of people. There will be a focus on environmental causes of public health problems.

Ecology - Students will answer questions involving content knowledge and process skills in the area of ecology and adaptation in featured biomes.

L3.p3 Factors Influencing Ecosystems (prerequisite)The number of organisms and populations an ecosystem can support depends on the biotic resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition. Ecology - Students will answer questions involving content knowledge and process skills in the area of ecology and adaptation in featured biomes.
L3.p4 Human Impact on Ecosystems (prerequisite)All organisms cause changes in their environments. Some of these changes are detrimental, whereas others are beneficial. Ecology - Students will answer questions involving content knowledge and process skills in the area of ecology and adaptation in featured biomes.
